'65 D100 drum brake sizes

[Volksnut]

Picked me up a '65 rear axle for my '63 so I'd have rear e brakes. On checking the shoes, drums etc. to see what I'd need to replace the sizes aren't matching up to anything I find listed. The drums measure in at 10" diameter and the shoes are 2 1/2". Does that sound right? I was reading they were supposed to be 11 x 2

Sounds like a B-body passenger car brake.

11x2 is correct for rear of 65 D100

A series vans had 10x2.5 on rear

I guess the 10 x 2 1/2" shoe fit a slue of different vehicles, from AMC, Dodge, Fords etc.

Is it possible to swap out the backing plates and drums to convert to 11x2?

Anything is possible, the '63 axle is still in the car so the drums are the same id have to get everything else.

the axle assembly must have been swapped out with van axle at some point

I was also told it could be a later '70 axle as they came with 10" x 2 1/2" rear drum with front disc

Yes^
I may have posted that in another thread. 70/71 show 10"x2.5"
