I am starting all over again on the body for my 76. The original tub turned out to have a lot of patches, repairs that were done terribly and too many rusted areas which was not good enough for me to start a restoration.
So, I got a complete unassembled body kit. Looking back now, I should have saved up for the complete body tub instead. More money up front, but about the same in the end.
The Dynacorn body kit does have the Firewall/Cowl section complete in about 10 pieces already welded together, so that is a great starting point. They also include a one piece floor pan that further helps the process and deletes some additional work.
The measurements posted for the door openings are a great help as well. Obviously the measurements overall had changed some over the years and do not need to be as exact as I would have expected. We can mock up as we go and fine tune the fit as well.
The Body Kit is at the body shop for assembly, but I have been taking my 77 over, which has all original body, for comparison and measurements. This gives me a better standard than the 76 body which is not so good to go by.
Keep you posted.
