I wouldn't think the 6th gens are compatible with anything else or the fbody rear ends since it seems noone I swapping rear ends on these cars except from other 6th gens (v6s, auto - m6, ect)

I think the Gen 5 ZL1 difs will work as Chevy suggests them for drag cars, but they are super heavy and also 3.73s.
The gen5 1le diff will not live long with more power and a sticky surface. Ask me how I know. :(
