oh, I see then. You are going to do the frame FIRST and want a good donor. Hmmmm, I would look first at the equivalent B bodies from Pontiac and Buick, double check the frame measurements; width at crossemembers and axle, length from front to back, length from wheel to wheel, etc. There might even be a frame specialty place on the web that has that info already. I know that is what you are asking but and you have probably already searched but....

While you are at it, you might also look into going with front disc brakes. My Delta didn't have them and I am not sure if that was an option that year for the B bodies, don't think so. I am sure it can be done.
