I have a S2.93 in my S50 swap with ZF 5 speed and want to go with a shorter rear end for autocross. Locks well, no noises, fresh fluid. If you have a good condition S3.15 or S3.25, 6 lug input, medium case diff and would like to swap, let's have a few beers and swap 'em out! I'm in Oceanside, CA and have space for both cars to be up on jack stands.
