When I first looked at the rear end in my 72 I thought it was a 9" ford,but the previous owner said it was out of a 57 chevy. Looks like it bolted right in and works great. Anyone know the history and strenght of these rearends?
They used it from 55 to 64. It's not a real good deal the caps have a bad habit of blowing off the center section. The rear end of choice for 57 Chev was the 57 Olds or Pontiac. It is a really heavy duty rear end but I haven't come across one for sale in years.
You can normally get a 12 bolt out of a truck pretty cheap. I have one and plan to cut it down to size and put a Detroit locker in it to replace the 8.2" ten bolt that I currently have. That will be a project after I get my project on the road. For now I figure I can run the 10 bolt till it gives out or I get enough money to do the 12 bolt.
there is nothing wrong with a 10 bolt for a street car. if your going to be out at the drags all the time trying to pull wheel stands then you will want to step up to a bigger stronger rear end like a fab 9 or dutchman something purpose built.
