One of Dan's suggestions that I liked was to make this a full frame car so the body can be removed in order to powdercoat the chassis. I'll get rid of the round tube stuff that was added in which I highlighted in the large blue oval and tie the front and back chassis together with the same tubing used by AME. The tie in within the small blue oval will be left though I prefer to use something other than round tubing since it just doesn't fit well visually with rest of the frame.
Then we'll cut the frame loose from the body in the only other point it is welded in, which is where the cross member hits the rockers. See area highlighted in red.

I'll put plates on the ends of the frame crossmember and matching plates in the rockers and have it bolt in there.
Then we'll cut the fuel cell "cage" that was fabricated loose and move it forward a few inches in order to trim the rear frame rails to the proper length and move the cross rail back so it can sit behind the tail panel without interfering with the bumper mounts as it does now.

Once these are located properly, I'll put end plates in place with bolt holes that will allow the endplates, body and bumper supports to all be held together with the same 4 bolts on each side.
