4th gen rear swap today :)
Picked up a 96 z28 rear end yesterday. Rpo g80 / gu2
So 2.73 gears and an Auburn LDS
Got to work first thing in the morning and had it in before lunch.
Now just need some better rims

Re: 4th gen rear swap today :)
Nice! I remember how excited I was when I put a 2002 Z28 axle with 3.23 gears. It too had Auburn LSD. I'm upgrading the Auburn LSD to a Eaton TrueTrac. Also, I'm thinking of going up to 3.73 gears. You might want to lose that Auburn unit too, or maybe burn it out first? Lots of info on TGO about how the Auburn unit is not rebuildable.
Your tires sticking out about another 5/8"???

How much room between the fender lip and the tire do you have now

Re: 4th gen rear swap today :)
Try adjustable panhard bar before adjustable LCA's... I remember similar issues after my 4th gen diff swap. It's trial and error to get the centering right depending on tire sizes, suspension parts, bushing type, etc.
I remember trying to space the tires to the body equally while adjusting the panhard bar, and it was still off center. Good luck.

The 4th gen car I took it out of was wrecked from that side I'm now thinking that the diferential might be bent cuz I measure both sides of the wheels and it's about 5\8 difference
