Jerry---There is merit in what you say. Let me enlarge a bit on my previous post. As you pointed out, the glassing should be done with the car on the frame.---That is to say, the inner glasswork. and then after it "kicks"---Everything I have ever read or studied on the creation of fiberglass bodies, or of glassing a floor into a T-Bucket style roadster,is very clear on the fact that an added floor, be it glass, plywood, or anything else, be glassed and tied into the main fiberglass body from both sides, to give a "sandwich" type of construction. This not only gives tremendous additional strength to the body, but also seals whatever is used as the floor material against moisture.---Brian
