Anyone know if second gen. camaro rearends will bolt into a 69? Are they the same width? I have a 69 that has a GM disc brake rearend, single piston calipers. I need to identify it. I pulled the numbers off of the axle tube a couple of years ago and had no luck finding a match. I'm working on this project again after a 2 year break and need to figure this out. I don't have the numbers right now, that half of the car is 130 miles away. Did the early 2nd gen Camaros come with rear disc brakes?
