Thanks for the info. I have a '66 Catalina 2+2 with 3:08's. I am looking to increase them to 3:42 or 3:55's. An individual who I met at the pure stock muscle car drag race at Stanton, Mich. who was racing 65' 2+2 similar to mine was telling me that '65 & '66 were "bastard" years as far as rear ends go. I didn't really understand what he was getting at, but I think it had to do with Pontiac making 10 bolt ring gear sets mounted in a 12 bolt carrier. He told me that there was nothing available in the after market to fit this type and style. I will definately contact Richmond gear about this. Thanks again!
