Thanks guys. For now I'm going to take the easy way out and use the offset plate I fabricated. Will move the diff 1" to the rear....hopefully it won't foul up the spring geometry too much. Lot's of "if's" with this diff...it's an Australian Borg Warner 9 bolt from an 88 IROC-Z V-8 stick Camaro...3.08 with posi and discs but it was 62" like the stock torque tube diff so will give it a shot.
Once again...I appreciate your input and have some good options if my setup doesn't pan out!
