My name is cole and i just joined this site. And I just bought a 79 Z28 with no engine or transmission. But I also have a 73 camaro with a 350 in it and I am going to put that engine in my 79. Anyway I'll get to the question which has nothing to do with any of this I just thought I'd give you some backround info on me. What gears would a 79 Z28 posi rearend have in it?
