I will be mating a 1964 vintage 3.03 ford truck toploader 3 speed to a 309ci Y with 11" flywheel to go into my big window 56 F100. FYI, I want to keep "3 on the tree" but have all synco trans that can take the additional ponies. I have been told to get the newer style pressure plate "with fingers" instead of the old style. Who makes these types of pressure plates for the y-block? Also, what brand(s) make the best clutch disc? Where is the best place to purchase this type of clutch? Thanks ahead for the help! Greg

I should add that the 3.03 toploader 3 speed was mated to the 292 y-block in the 1964 f100's. So I can just get a clutch kit for a 64 truck with this combo. I just want to know which brands people are having the best luck with and which ones have the newer style pressure plate. FYI, the input shaft is 1 3/8" 10 spline. Thanks again! Greg

There are three basic styles of pressure plates. The original equipment style was the ‘Long’ style which had three fingers. Another style that was popular in its day was the ‘Borg & Beck’ which has three wider arms than what's found in the 'Long' style. The replacement pressure plate that are much more popular now is the diaphragm style which have a multitude of thin fingers placed close together in a circular pattern. The ‘Long’ style are getting more difficult to get so the diaphragm pressure plates are becoming the best if not the only choice. I have a local brake and clutch shop that is good at getting the newer clutch disk and pressure plate combinations for the older vehicles. For my ’55 Customline, I simply ordered a clutch and pressure plate for a 1967 Fairlane with a 289 and received a diaphragm style setup that worked perfectly. I already had a transmission with a 1.062” input in the ’55 which is the same as the ’67 Fairlane so this was a bolt together. If you have a good parts guy available, he (or she) should be able to match you up to a suitable replacement setup. You might try checking your Yellow Pages for clutch and brake shops as these have been around for awhile and can be quite helpful in these instances.

The truck's 1 3/8 10 spline clutch in stock form is rather difficult to find. An aftermarket or modern style will be near impossible. I found a stock replacement clutch at Carolina Clutch.
What have you done to the engine? The stock 11" clutch seemed to do fine with mine.

Ted, Charlie,... Thanks for the replies. Ted I have spoken to my local parts guy and he can get a LUK brand stock replacement clutch kit. He doesn't know if it is the diaphram style or stock style without ordering it. It would be special order so I'm trying to gather info before ordering so I get the best stuff. Charlie, I will look into Carolina Clutch. I have one of their HD disc's in my 04 F350 6.0 diesel and have had good luck. The engine is a Tim McMaster built 292 .30 over with 312 crank. Street ported 113 heads with 2.02/1.6 valves, 1.54 rockers, cast flat top Badger pistons on C2AE rods, 0 decked. Cam is .450" lift (with 1.5:1 rockers) 288* adv. dur. and 238* @ .050 with 112* lobe centers. The stock style clutch will most likely work just fine. I had heard that the diaphram style pressure plate is superior and read/heard some brands of clutch discs are better than others so I'm trying to get info on what brands have worked well and possible sources for those brands. I have not heard any bad things about LUK clutches so if this is the only thing available I will go with it. Thanks again. Greg

I don't know about the LUK clutch, but one problem I ran into here is that the local parts stores have a 12" clutch kit listed but when I actually got it in hand, it was for a big block, which will not bolt to your flywheel without drilling new holes. Zoom also offers one but it's the same story. In fact, the local parts stores part number was suspiciously similar to that of the zoom clutch, MU72112-1.
Give Carolina a shot. We probably have very similar power output. When I was using it, I had no signs of slippage.

Thanks for the replies Charlie and 314, 314, I have been to John's site many times before but must have missed the pressure plate and disc, so Thanks! He says "Exchange only" on the disc and I do not have one. Unless the stock 1956 light duty 3 speed has the same 1 3/8" 10 spline clutch??? Anyone know? Charlie, I went to CarolinaClutch.com and they list a LUK clutch kit for 61-64 f100. It does not list the size diameter or shaft size/spline count. Curiously, at the two local parts stores I checked, one store listed a 12" clutch and the other a 11" clutch for a 1964 f100 w/3 speed. So, I will check your part# against theirs and see if they match. I appreciate all the help! Thanks, Greg

Try a Centerforce. They have lots of combos with 1 3/8 hub, 11 inch. Jegs, Summit have them. I bought one from a company called Street Side Auto in Kansas. ( www.streetsideauto.com ). Very good service, the right item and best of all, the best price. I tried Jegs for one, Street Side beat jegs price by about 40 dollars plus they were running a special for an additional 25.00 off.. Mine is a dual friction model which looks like a good street clutch. Car is not on the road with it yet. Go to the Centerforce web site and you can see what they offer. Give disc size, hub size and shows the application. The tech line was very helpful since their apps don't go back to 56. My hub was 1 1/16 so I cant give you a app.

Thanks Paul2748, I called centerforce today and they said there are several different bolt patterns for the 11" clutch. Since I'm at work I will have to measure tonight when I get home and call them back tommorrow. I appreciate the input.

Greg, I believe the 11" Y block and FE flywheel bolt patterns were the same. I got one for a 63 Galaxie with the 406 and it fit my y block flywheel but that is the 1 1/16" 10 spline. I have taken out several 11" 1 3/8 10 splines out of larger trucks, box vans, etc with Y's. It is a fairly common size and I think any of the larger trucks with I6's also used this clutch. You may need to look into ordering for say F350 and above.

I'm also considering changing to a centerforce clutch in my 56 Victoria with a 292 3 speed. Does anybody know what size clutch would be in this car originally. I would like to order what I need before tearing it apart. Thanks Dave.

I'm also considering changing to a centerforce clutch in my 56 Victoria with a 292 3 speed. Does anybody know what size clutch would be in this car originally.There’s no guarantee that the parts in your car are original at this point in time but here’s the information from the Ford parts catalogue on clutch sizing. 1954-1957 Ford car 239/272/292 --- 10” 10 spline clutch disk. 1956-1957 Ford car 312 --- 11” 10 spline clutch disk. 1958-1959 Ford car 292 --- 10” 23 spline clutch disk. 1955-1957 T-Bird --- 11” 10 spline clutch disk 1954-1957 heavy duty 239/272/292 applications --- 11” 10 spline clutch disk. 1958-1959 heavy duty Y applications --- 11” 23 spline clutch disk. Heavy duty refers to Taxi Cabs and Police Cars

All Ford trucks that I have seen used the 1-3/8" 10 spline hub through 1964. That hub goes all the way back to the Model A. I don't know of a diaphragm pressure plate that is compatible with the 1-3/8" hub. The one we sell is for the 1" or 1-1/16". There can also be compatibility problems with the thickness of discs between cars and trucks. The 1-3/8" truck discs are thicker and can cause slipping or release problems when mixed and matched with car pressure plates. The 427 Toploaders used the 1-3/8" input shaft so some high performance parts might be available.

Thanks everyone for your help. It looks like I will have to go with a original equipment style clutch. (Like Charlie Mc said). I called Carolina Clutch and LUK clutch, they only have the 12". I called Street Side and Auto Com, they have orignal style clutch and say it is 11" but did not have all specs to compare with. Also, most of their clutches are imported (can you say Chinese). I talked to Centerforce and they had to put together a combo they thought would work but were not sure if the clutch fork angles and depth would be the same with diaphram style pressure plate. And I also talked to my local parts guy (Napa). They confirmed with the manufacture (made in USA) all the specs and measurements. So, I decided to keep it simple and go with original equipment replacement from Napa. They are a little higher in price but the parts are american made and I keep my business local. I appreciate all the help and support. You guys are great. Thanks!!!

I think you should try Centerforce if they think they can put one together. You might call them and say that you know someone who is running an a 1990 Centerforce Mustang clutch , Centerforce part #DF021048, in his '61 F100 with the same engine. I am having a problem with my clutch linkage which is that the adjuster rod is too short for the parts I am using. I'll have to make it longer before too long.
Your stock throwout bearing will be longer from the face of the bearing to the fork groove than mine which should give you a considerable amount more adjustment to work with, assuming that the pressure they pull for you is at least as thick as that of the mustang clutch above. Long story short, I think you'll be fine with what they have to offer and if you need a longer adjustment rod, chances are I'll have a solution figured out by that time.
And as an added benefit to others, we will know what part numbers to order to get a good aftermarket clutch for the trucks.

On Charlie Mc's advise I called Centerforce back. So, here is some more information. When I spoke to Centerforce again, and after considerable discussion, they came up with part # DF-559000. This is not a direct application but is a diaphragm style pressure plate with dual friction clutch disc kit designed for Mustangs, Torinos, etc. with a 429 and toploader 4 speed with 11" clutch. (I think this is what John M was eluding to). Again this is 1 3/8", 10 spline input shaft with 11" clutch on flywheel with three sets of (2) 5/16" bolt holes. The bolt holes are 3 3/8" apart center to center in each set. This part # should work with stock Ford truck throwout bearing and pilot bearing (up to 1964) with no problems according to Roger at Centerforce. Also, I was referred to a clutch shop in San Jose, CA called Superior Friction by a friend who owns a hotrod shop. I spoke to Robin at Superior Friction who was very helpful. He says he knows and has worked with John Mummert in the past and has put together this application before. He is going to call me back tomorrow with more info on a package he can put together (It includes a diaphragm style pressure plate). I will post here after I speak to him. So, it looks like I will cancel the Napa clutch and get one of the two mentioned above. I will keep you posted.

Charlie, Years back I broke the adjustment rod on one of my '57's,I had about 10 threads left on the end so I bought a 1" long threaded union,12" of all thread rod,2 large nuts(for adjustment),and a lugnut with a concaved end.Threaded the union on both pieces then welded both sides so they wouldn't back off,then added 1 of the large nuts and the lugnut and extended the rod through the clutch arm about 2" and added the other large nut and a lock washer. Had plenty of adjustment after that and never failed me once for the next 10 yrs(sold the car).I know it's a little backyard but I needed a quick fix to get back on the road and it lasted forever!

Update: Robin at Superior Friction in San Jose, CA put together a clutch for my combination that includes, a diaphragm pressure plate, kevlar and organic clutch plate, throw out bearing and pilot bearing. He tests every clutch combo before sending it out. He is a one man operation but is extremely knowledgable and very helpful. I reccomend him highly. His phone # is 408-436-1101.
