Hello, I'm selling a complete 1971-76 B/C 3:23 posi (minus brakes). A member from Florida is interested in this. He has a 1972 Riviera (E-body, I believe). He's under the impression that this rear end will bolt in his Riviera. Being I'm not sure, I don't want to sell/ship it from Ohio if it isn't. Any help will be appreciated. Here is the link to my add. Thanks. http://www.v8buick.com/index.php?threads/71-76-9-3-8-3-23-posi-rearend.326509/
About 30 years ago I installed a 9 3/8" rear axle from a 73 Riviera into a local customer's 74 Olds 88. The fit was exact. I just checked my Buick parts book and the axle shaft part numbers are the same for 71-75 B,C,E with "O" axle. ( O axle is the 9 3/8", so you should be ok. Hope this helps. Clark
Wow, the potential buyer told me that he thought it would "bolt in" but I was leery. It's amazing the the knowledge that's out there. I'll pass these information on to him. Thank you GSCLARK.
