OK so last week we moved the body of my 57 onto the "new C4 frame". At the time we installed new polyurethane bushings and new body mount hardware, but it is all just on finger tight. I need to do some rust repair in the outer rockers, floors, and trunk pan. Then I will be replacing the dash and doing a recessed firewall. My thought is I need to get the body bolted down and the door and fender gaps as good as possible before I start this process. I have seen some shimming guides on door gaps as well as guides on setting front fender cowl gaps, but these are on cars that are assembled. Where is the best place to start? OR do you just pick a place to start and keep working around until it gets as good as possible? I am sure that this will be a process but just thought there might be some insight from those who have done this before. Thanks Mike
