741 x housing

Is it leaking? If it ain't broke.
I have a few pre-65 rears, nothing wrong with them.
Definitely needed a hub puller to swap to 65 drums, now the drum and hub are separate and can pull the drums off same as 65 and up.
I pulled the axles from one by removing the backing plates, putting the hub back on loosely, and hitting around the back of the hub with a small hammer, popped right out.

While we're talking about pre-65, the ball & trunnion 'u-joint' is bulletproof, imo.
I've had u-joints fail, but never a b&t, even with a ripped boot and kept driving it.
