Ratech Manufacturing has shims for most differentials-- for the 8-1/4 their part # 1100 ,,, can be ordered direct or from Summit Racing---- another option if you know any one that has set up an 8.8 rear axle used in Mustang , trucks etc. --- the 8.8 uses the same pinion shim
I do know someone and he is just over the hill with a couple 8.8 rear ends laying around :) Thank you and I will give them a try, I sure am glad I received the help I needed before my day got started :thankyou:
