Hi guys As subject line says, can someone tell me the distance from backing plate to backing plate? Also, from center of one spring perch to the center of the other? This would be for a '55 sedan (or 56 or 57). My car isn't where I can get to it right now to measure. Thank you Missouri Mike

I was just setting up my rear end the other day in my '55 Ranch, I assume they are the same? 83" spring center to center. Don't know about the backing plates, I'm running a 8".
Sorry, should be ~42".

I am so sorry, one of those Old Folks Moments... should be 42".  Thanks for calling me on that.
I remember the numbers because the bushing were wearing out at a wierd angle. The 8" that was installed in the car turned out to be 43" center to center. Wasn't a happy camper.
As maxwell Smart would say "Missed it by that much".

Thanks a lot guys. I searched several times and I saw a lot of this will fit, that will fit but I never saw any actual numbers. I've located an older 9" that's 43" center to center on the perchs and 50 1/4 " backing plate to backing plate. So if someone can give me backing plate to backing plate numbers I may have found a rear end for my 55 Customline. Thanks again Missouri Mike

Mike, where are you measuring from "backing plate to backing plate? Out of curiosity I just went out and measured my 8" and it is 52" flange to flange. I will I do have difficulty installing ires between the axle and fender.

Thanks again Missouri Mike Mike, the 57-59 9" diffs are within 1/2" of the original overall width and the saddles only need moving slightly. i have seen many that force the springs across to suit the orig saddles, not good practice. regards bill.

Mike As Aussie Bill said 57/59 Ford 9 inch is 53 1/2 flange to flange and 43 spring perch to spring perch. This is also very close to 65/66 Mustang 8 inch which is much easier to find. Pete

That's the way mine was and it wore the bushings out at an angle. After replacing the bushings and anti-squeak pads I could not get it back together and the rear shackles were no where near close. Screwed up the lowering blocks also.
After everything was tightened up with new parts the 1" difference was too much to "force the springs to suit".
Like Aussiebill says, "not good practice".

I've read where the 57 is reeeeaal close and was kind of hoping that was what this was. I've not measured anything, these are the measurements the seller is giving me. He doesn't know what it came out of either. According to him, these are the measurements, From outside brake drum to outside brake drum is 57 3/4". Between the brake backing plates 50 1/4". From the center of one spring perch to the center of the other 43". Does this sound like a 57???? Or something close??? Do you know of any other 9 inchers that would fit? I don't want to have to force it. I found out a long time ago that's not a good idea. I would probably use plan B, although I'm not sure at this time exactly what that would be. Thanks again Missouri Mike

Try this site. I've been told that the 57 9" is the same dimensions as the 56. SO I would suppose the 57.25" is correct. If the spring pad locations are only slightly off some people have redrilled the center pin hole offset to correct it. Chuck http://www.mustangsandmore.com/ubb/FordRearDimensions.html

Thanks again Missouri Mike Mike, the 57-59 9" diff will fit with the saddles moved slightly as discussed, there is only about 1/2" overall width difference and is what we use here for years in 55 56 ford customlines. regards bill.

Mike, do as AussieBill suggests, move the pads before you install it. Since mine was already installed and I was going to lower it I fabbed up some 2" lowering blocks with a 1/2" offset of both sides.
