CobraV8-
First and formost your piniion angle should never be "positive" (Pointing upward-massive wheel hop problems!) under any circumstances! You can cut both axles to center the pumpkin but that really isn't necessary. The car is originally built to the stock 8.8 rear and it is offset to begin with.

When I order a custom 9" from "Currie" or whomever I tell them to weld in the exact same brackets as the 8.8 and in the exact locations, including shortening the one axle tube to the same as the 8.8.

When done your 9" will look just like an 8.8 except you will have the 9" pumpkin.

Pinion angle should be a minus 3 degrees, +/- 1/2 degreee. Again depending on your HP, TORQUE numbers, traction and how hard and long you intend to -stay in it- at launch. The higher the torque/HP, the more traction you get, and how hard you launch- (I.E.;1/4 mile racing) can equate to a full 3.5 degree negative angle.)

Scott is in the middle of correcting his engine and pinion angle right now. It might help to glance over his thread.
