What I was referring to was a complete assembly, everything from the rear frame rails to the front frame rail supports. Dynacorn and at least one of the major companies make these assemblies for the 65/66 vert as well as coup and fastback of all years. I have not seen one for a 69/70 vert but I am sure someone has a complete assembly. There was a company that was assembling & selling the 65/66 before before Dynacorn and the others, they would build others upon request. Can not seem to find the company name at the moment.
Just found it, Thoroughbred GT (http://www.thoroughbredgt.com/ 330-533-0048). They may now be out of business or the home page URL has changed. May be worth a phone call the phone number still works, 330-533-0048. If I were working on a car with that much rust if I could get a quality fully assembled pan I would jump on it in a heartbeat. It takes a lot of time and dedication to do the work right, what is your time worth TO YOU.:
