Have 63 riveria,took the american 18" tQ thr. off to replace with some 15" chevy truck rims with 5 on 5 bolt pattern. The center hole was inlarged fot the chrome bullets, the bolt pattern was good. The chevy rim would not fit over the buick finned drum brakes. Was not aware of that problem. Can any one suggest what rim is used or what inside Dia. 15" dia rim I should use? The rims I have are painted Silver metalflake with Bullet centers,bullet lugs, and chrome beauty rings with wide whites all dressed up, and no place to go. I did try the rims on the car to make sure the bolt pattern and center hole was correct, just didn't push the rim all the way on to check the clearance for the buick finned drums. Any help Thanks Riveria Jim
Read the sticky at the top of the page. Do a proper intro and then post your questions on the general discussion page.
Take the finned drums to a machinist and cut a little of the fins off to get the clearance you need. Almost sacriligist to do this but it might be your cheapest alternative.
