Technical Yet another brake drum fit question

> Could put the spacer on the axle, between the flange and the bearing.
Possibly, but then I'd have to think about bearing load since the bearing race wouldn't be fully seated in the axle.

I was thinking of a spacer between the axle and the drum, sort of like a wheel spacer. With a 2.43" recess for the axle and a 2.77 pilot on the other side for the drum. In fact, I was calling QP to see if I could get a kit with a small bearing Ford backing plate and a large bearing ford drum. When I told them my measurements, the tech said the 2.5 offset would work for 2.36. I'll find out

My pops has a rearend set up by Winters, and configured to use the Lincoln style brakes from Boling Brothers. It has a small spacer between the axle flange and the bearing, probably to correct the offset distance so it matches the old style brakes and drums.

A couple things to note, you need to measure the retainer/backing plate bolt pattern. This will tell you some useful information.

That will let you know if it's a old small bearing, old big bearing or new big bearing style.

The new big bearing would,if I remember correctly would be 1972 or newer.

Old big bearing would be a big car or truck, small bearing would be small car, falcon, mustang etc.

Axle tube diameter and style would also help narrow it down, 60's galaxies were large tube with long flat's down the top of the tube.

Your offset is kind of standard for pre Torino new big style bearings.

What is usually done is the axle removed and the bearing, backing plate etc is removed, then a spacer is pressed on then the bearing is pressed back on along with the backing plates. This gains the 2.5" measurements.

@anothercarguy had issues and ended up doing stuff to his backing plates. I admire his perseverance, but dang! Anyway, That thread might give you more info, even though it sounds like you have plenty!

 

Thanks @RodStRace.. this is the thread with the issue I was dealing with...and the way I resolved it.

The shop rebuilding the center section, who I trust, said the axle was from a 1969 F100. But with the small bearing Ford flange and the 5 x 4-1/2 bolt pattern, 2.36 axle offset, etc. I think I may have a Frankenstein axle. With other things I've uncovered with this roadster I wouldn't be surprised. It does make for an interesting time

Anyway, it seems like Quick Performance may have the solution (using mostly off the shelf parts) which works. I'm getting together a list of parts, part numbers, and supplies to live with the car to make it easier on the next owner. (Which I don't expect to happen anytime soon, but just in case...)
