So my car was the stock 326 with an open rear end. Now it has a 455 I just put a new quick fuel 750 double pumper on. The thing runs like a striped [censored] ape. But it does desperately need a posi rear end and I’d really like to have like a 3.23 geared posi. So I’m wondering should I buy the components and modify my current rear end or should I buy a bolt in Moser or look for a posi out of an early 70s Nova? I think trying to find an original direct bolt in that I don’t have to worry about is going to be a little more difficult.

So fellow Firebird owners I need your expertise and advice. If anybody has a good bolt in solution for me that’s within 200 miles of St. Louis give me a holler. Otherwise please let me know what you would recommend and where are you would go to get the parts needed to incorporate your suggestion.
