Options for Borg Warner Rear end ??????????

What kind of options do I have for gears and posi carriers for my Borg Warner rear end (RPO GW6)?? I heard a rumor that the 7 5/8" gears work in these rear ends. If that is the case, what about carriers??

You can only use 7.75 gears and parts. And everything up to and including 4.11's are availabe as well as new carriers.

What do you need? I can get it for you.
