I am moving to the next phase on my '63 Dodge 330 build, and plan on a Dana for the rear end. I was wondering what some of you may have used to replace the stock 8-3/4 ? Will any, or most of the later year B-Body Dana units fit directly, or will they need to be shortened, or modified ? My stock unit has been sold, so I can't do a direct comparison with what I can find used, and my notes & specs on it have been "misplaced". While I am asking, what Dana units would fit a '65 Coronet for similar needs ? Thanks for any help or knowledge you can offer...
