I've got a 66 goat 4 speed car .
Engine is about ready to go in .
What rear dif did they commonly put in these out of the box ?
What numbers on the rear end would I look for and where ?
Ultimately we'll probably take the cover off anyway but curious about what gm was putting in these cars for gears

BTW, if you have the PHS for your car it will tell you what deferential gearing your car was born with, if originality is important to you.
