Hi, Can you use a 12 bolt rear end in a buick GS and still pass tech inspection at any F.A.S.T. or stock appearing event? Thanks

OEM appearing aftermarket housings are OK. Internal modifications are OK. Any gear ratio allowed. Aftermarket axles are OK. Upgrade to posi-unit or spool is OK. I believe they will accept GM as the manufacturer of both Buick and Chevrolet so the 12 bolt should be acceptable.... but that's just my opinion. I'd ask on the F.A.S.T. site just to be 100% sure.
