    I hope ALL you guys know that there is NEVER a guarantee that the original set of gears with pinion bearing and shim intact will match your set-up in a different housing than the gears came from...IF you are just bolting these ring and pinions in with out checking the set-up you are living on borrowed time so PLEASE be careful on how cheap you are on setting up your differential ... Bearings should be replaced with NEW and pinion depth checked for correctness in every housing. Original shim is great for a check and see where you are on set-up but never guaranteed to work in every instance. Please reference www.jdrace.com and or this v8 B uick site GOT GEARS for more rear differential set-up know how.
    Thanks, Jim Mitschke

    If you guys buy a gear set and need a bearing to hone out etc. we might be able to help as we are always tossing bearing good enough for that... IF we have them available at the time of purchase.
