Sounds to me he still has a lot of issues to work out. Steel or glass, coupe or vert, etc. A firm decision is what is needed, and that decision will many times dictate the best body and parts. Not an easy decision either because both have their strong points. If he has the time and money tell him to build one of each, that way he would have to make the decision on which one to drive today.

OBTW, there is also Bear Fiberglass. They make a number of glass bodies including a 32 3WC and a roadster. They use cool car ceramic insulation in all of their bodies and are out of Prescott AZ. There is a member here who is a builder from there who swears by them. I can't offer a personal opinion on them because I don't own one. But keep in mind it is always best to shop around.
