I have the chance to buy a 12 bolt rear end with 4.11 gears and a posi for my El Camino. Right now I have the 10 bolt 8.2 back there with 3.08 open diff, so you can see why I want to upgrade.

My question is this, will it be a hastle to make the rear end fit my car because it came off of a 1966 chevelle with the flat ended coil springs and I have a 1969 with the pig tailed coils.

Anyone with experience in this I would appreciate it.

Never mind, upon further inspection the rear end will bolt right up no problem. He had it on his 66 but it was off of a 69 so it has the perches for the pig tail springs already.

Thanks for the replies though......

For future refference a 64 to 67 rear end in a chevelle is slightly narrower than one for 68-72. They still bolt in the same. They are great if you want to use slightly wider tires, gives you a bit more wheelwell space.

Thanks a lot, yes, I knew about the narrower length but I didn't mind that. I actually have 275/60/15's back there now and I figured I could squeeze 295's with the narrower rear end. That's ok, the 275's are pretty stout as they sit.
