Now that I'm aware the front yokes at the rear of the transmission are different for the 1/2 ton and 3/4 ton trucks (thanks, jorb), I was wondering if the retainer (I've been calling it a cover) (4.317 on the diagram) the same or different between the 1/2 and 3/4 tons? Also, see Tony292's first post for picture of retainer. Thanks.

It's a small world, but I wouldn't want to paint it.
