What parts are needed to convert a 62 Dart to an A833 4 speed? I did some research but I want to be sure before I commit. Does it have to be b-body A833 from a specific year range? It looks like Brewers has parts available if you contact them. I imagine used parts are out there. Are certain parts used only, like shifter handle, floor hump, etc? I know I'll need a new driveshaft, and I'll need to find a rearend.
