To my knowledge they are the same center.

It has the Corolla drums on it at the moment, although on the other one Im keeping I fitted Stanza Drums and adapted the 1200 handbrake setup. Im sure you could fit 1200 Handbrake setup to it.

You would need to replace the brake shoes, but the drums are OK, and the steel brake lines need replacing

Plus from memory I moved the mounting plates where it sits on the leaf springs, but this is no big deal. Could move and weld these for you.

It still has swaybar mountings on the housing, but can easily cut them off.

The diff I.m keeping is a 4.3 but they cone in 3.89 as well
