I'm with ya on this one! I find it almost impossible to get one together without big problems. I was doing final assembly on a 32 Ford about at hour ago. Despite close to a million mock-up and test fittings, and after making sure it was just right, the body and firewall dont fit the frame properly. I had to put shims on top of the frame to square up the back of the body, and the firewall is being completely redone. Aaaarrggh!
