redreattaruss Posted December 16, 2012 Share Posted December 16, 2012 I have some brake drums from 1963-1965 Rivieras. Some cast iron rears have a larger 3-3/8" center hole while other rears have a smaller 2-3/4" hole. The aluminum fronts seem to have the smaller hubs, although some have left hand threaded studs. Can you Buick experts help me determine what year Buicks used which drums? Thank you. Link to comment Share on other sites More sharing options...
60FlatTop Posted December 16, 2012 Share Posted December 16, 2012 '63 and '64 have the large openings. I glass beaded, epoxy primed, and black finish coated a pair of the small opening rears for my '64 before I learned; threw them in a lathe and took care of that little problem.Bernie Link to comment Share on other sites More sharing options...
1965rivgs Posted December 16, 2012 Share Posted December 16, 2012 Left hand studs should be `63 and older Tom Mooney Link to comment Share on other sites More sharing options...
