I want to have rear disc brakes to compliment the front powers that will eventually go in as soon as we find a donor car. But I also need a new bigger rearend. I wanted to know if I could possibly kill two birds with one stone and pick up a 9 inch rear with disk brakes still on the car. If, which car has a compatible rear end for the 65 and had factory discs? Is this possible? I just don't want to spend 1K on rear disc. Thanks
