Everywhere I searched people said a 55/57 chevy rear end is a bolt in replacement for the 50 chevy car to open up the enclosed drive line.

Well, today I placed the 57 rear end on my original springs. Got the pins lined up with a little grunt work only to find out the rear end sits 2 inches farther forward then the original rear end.

Now what?

If I re-drill the pin holes on the 57 pads it will change the pinion angle because it rides up on the arch of the spring. The 57 springs are to long to fit the 50 mounts without manufacturing new rear spring brackets.

Anyone out there done this before?
