Did you buy a polara Tex? 62-63 diffs are 58 1/2 wide
68 b. Diffs are 60 1/8 wide

I know some guys on here are putting 275-295 tyres under there 63s without rolling the outer lip, I'm sure someone will confirm this. Ive got 3 diffs to choose from for my 63 polara, the original, a 31 spline 9" or a Dana 60....decisions.

no not yet . I do have a good offer on a 63 hardtop , just not sure if it is the 1 for me . I like too many of the mopars though a 64/65 Plymouth would be number 1 . I have a S60 in my Satellite and obviously will keep it .Essentially I am looking to do a full mechanical swap then sell the Satellite . And keep racing of course .
