Interchanging a FJ40 or '55 rear for a '60 rear. (1 Viewer)

[cruiser_guy]

Does anyone know if a FJ55 rear axle and a FJ60 rear axle are the same width? I'm thinking that the FJ55 and FJ40 are the same and the FJ60 is wider. Am I right? If they are the same width are they interchangeable or if not is the rear brake setup (backing plate, wheel cylinders etc. etc.) interchangeable. I'd like to go with the e-brake at the rear axle and full BJ60 running gear on the FJ55 rebuild.

55 drivetrain is in almost all if not all cases the same as Fj40. (Freak F 4 spd tranny that is pretty much nonexistant in US).
So disks+fine spline birf 76+
Fine spline R&P 78+ IIRC

FJ55's came out with disk axles in '76. I kind of expected that the FJ40/55 were the same and the FJ60 was wider .
Does andone know if I can swap the drum brake components over from the FJ60 rear axle to the FJ55 rear axle to give me the e-brake function at the axle rather than the transfer case?
