I have an '84 with the factory open diff 3.23 gears. With the new engine and rebuilt tranny I figured I'd refresh the rear end as well. Gonna use the stock housing and just get a posi carrier with some 3.73s. PM me if you have either or at my email address atorrefiel@gmail.com

do you have a 10 bolt or 9 bolt? 7.75 is a 9 bolt, 7.5 is a 10 bolt. if you have a 10 bolt i have a Richmond set i'll sell for $100 shipped.

Can't remember off the top of my head. Let me look underneath the car real quick and I'll get back to you.
