I have a problem with a rear end I bought to put under my 1952 chevy truck I'm building. I was told it can out of a1980 Camero and bought rear brake wheel cylinders for it and it will not bolt up. It hits the ears at the rubbers on the end. The old one was missing all the brake parts. I've found all the numbers on the rear end put cannot locate my numb ers in any sites I have visited. Maybe some one can help. Here are all the numbers. On passenger side of axle--PS G61052....... on right side housing,,,D76 and underneath.... N 1249518 B. What is this animal?????? Thanks.

Question: Are the lug studs ASE American thread or are they the Metric thread. Axle numbers do not mean much to me. However , if the rear end is out of a car in the late seventies or eighties then the rear wheel cyl. will be held in with those gosh darn stinking snap in clips ugh! I hate those darn things. If the wheel cyl are held in with the traditional two small bolts then the rear end is off of an earlier model. Does the rear end cover have a tag on it? Usually GM didn't use one except on posi units.

Post a photo of the rear, it is a leaf spring housing right?

Are you using new springs on that truck? If you aren't you will need to drill a new hole in the spring pad on the rear as the thru bolt is too far forward on the stock springs.

Thanks to Big Don for your help. Wheel cylinder is held on by ase bolts but will not bolt up tight to holding area, it lacks about 3/16 " touching tight.

Thanks fast 68 for your reply. The D76 is what I found too. Thats what I bought the wheel cylinders for that want bolt up tight to the mounting area, it lacks about 3/16 of an inch because the outer edge of the cylinder touches the ears on both sides which keeps it from mating up tight. It's a 8.5.
Leaf springs.
