Mopar 9 1/4" rearend
I'm also interested in this swap- I have one out of a New Yorker (only a little wider!) also sure-grip, but higher gears. I want to do cut it down for my dart but I think it might end up being more expensive than buying everything for an 8 3/4 (sure grip, axles, and gears)! hopefully some one in here has some ideas
