bigamericanboy Posted October 1, 2016 Share Posted October 1, 2016 Hello Everyone! I just bought a 71 Monte parts car. I'm picking it up in a week. It has a 12 bolt rear end and the guy that sold it to me said it was a 3.31 posi. He told me that Monte's didn't come with a 12 bolt that wasn't posi. I find this hard to believe. Does anyone have any information to back this up or disprove it? I'm hoping it is a posi rear end, but haven't tested it. Thanks!

Sam (Bones) Posted October 1, 2016 Share Posted October 1, 2016 most were not posi axles, my '71 was originally a 12 bolt 2.73:1 single legger Quote Link to comment Share on other sites More sharing options...
RealRed70 Posted October 1, 2016 Share Posted October 1, 2016 He is wrong. You can check the code on the paasenger side axle tube to tell what it was originally. Quote Link to comment Share on other sites More sharing options...
