I'm not the right guy to be answering this, but there are many capably people around who could. Where are you located, we might all know someone local or at least point you in the right direction.
Have you tried on RDC. Although beware of the masses of keyboard racers.
apparently it only takes some fiberglass bedsides and BAM they are giving their expert opinion on everything.
Do you have pictures of the car? Are you planning to come play with the VORRA crowd when your done?
Let us know. We can help get you some answers.
