That's what I figured, but I did look up and the OD of the bearing is supposedly the same. I'm wondering if new axles with green bearings would work. I guess I'll contact Dr. Diff next week when he's back from MATS.

The housing end bolt pattern changed in '62. Some folks over on the FL forum have mounted the later brake backing plates by drilling new holes and using aftermarket axles with Green bearings.

The bearing race diameter is the same but the flange axle bearing collar hits the inner seal in the taper axle housing. The Greens need no inner seal.

They drill new holes in the housing flange? I suppose that wouldn't be too difficult...

No, they drill the backing plate.

I tried to find the thread with pics but their search only goes back one year.

They have axles with the correct flange for the early axle ends?

Dont no about 57 but the 66 and up axles fit the 62-65 housing. The problem is the housing is not machined deep enough to accept the seal and bearing together. I have used late axles with green bearings and no inner axle seal.

If I remember correctly, you can't simply re-drill the bolt pattern on a newer backing plate as a 1957 housing end has a ROUND flange.

Could be. I haven't looked that closely at it.
