I'd really like to keep my 3.03 toploader 3-speed transmission in the car I'm putting a Y-block in. Are there any bellhousings and/or other parts that will allow this?

I believe Offy made one, i'm sure Hurst did too.. they pop up on eBay pretty regularly so just keep your eye peeled

I have one of these 3 speed toploader bolted up to my Y Block in a Mainline Utility.
It bolted up with minimal modification to my application using the original Ford Y Block bellhousing. My engine and bellhousing was a 1958 Australian Y Block and had four holes tapped/threaded across the bottom of the gearbox mounting surface. This came about as the Aussie Y Block Customlines of this year had a gear shift plate on the right side of the gearbox (mirror image of the earlier manual boxes). This meant that here in Oz you did not need to use a cross over linkage.
You need to cut a bit off the end of the gearbox input shaft to fit into the spigot bush. I think I cut off about 3/8 inch. I did the conversion a long time ago and can't remember exactly.
You may need to drill and tap a couple of holes on the bottom of the bellhousing face if the holes don't line up.
The two inner holes of the top mounting face of the gearbox will line up with the Y Block bellhousing.
I have read this forum elsewhere and read that it may be necessary to turn down the thrust bearing flange to fit the gearbox to the bellhousing.
I did not have to. This was a real bolt on conversion in my case and well worth the effort.
I hope this helps
Regards

I have (2) 3.03s. One came standard issue on a 63-64 Ford truck, so it bolts right up to a truck Y bell. The other came from a Mustang, and I am pretty sure it has the same bolt pattern. Input shafts and tailhousings are different between the two, but there may be some interchanges possible.

anyone know how many teeth the flywheels have? I might be able to use a couple of bellhousings I already have, one from an AMC V8 to a BW brand toploader and the other from an Y- 292 to a ford(o-matic?) Auto.
Don't ask me how I figured that out...we must recall 70s and 80s AMC copied 50s and 60s Ford. I realize this is one psycho thing to expect to work, but I really want to try. I need the flywheels for Y-Blocks to have 164 teeth for it to work...

The 64 galaxies and customs had a 3.03 that will bolt to a Y block bellhousing,64 was the last year for that bolt pattern and I found out about this when I put a 351-w in a 64 custom with a 3 on the tree.

The Y-Block manual flywheel ring gear is 146 teeth, 10 pitch. Small block is 164 12 pitch (finer teeth). Some toploaders have both bolt patterns and all have room to drill early pattern if it is not there.

Ah well, it was worth a shot. I actually can get a galaxie drivetrain for free, 1964. If only it wasn't Windsor and Automatic, then it would be perfect. You know how it goes.

Good Grief! Drill 4 holes in the front of that 3.03, shorten the input shaft about 1/4" and use it!

Looks like I have to, I was hoping to only drill and cut things that I have more than one of or are from something I don't need.

How about this; Has anyone heard of the Saginaw 3.25? I know it was an unreliable transmission, but that it had something I'm really fond of: The reverse gear is selected by putting the shifter into a spot to the left of first. I have a Volvo like this, it's my favorite car ever, I think it's just a cool layout for the shifter. Is this easy to link tot he Y-Block?
