thanks for the great ideas!! realy like the one with the BBQ hinges.
anyhow, you take square tubualar steel, weld it from the front pillars, to the rear roof, two across the top, under the targe pannel. while strenghining the chassis. I did forget about how the doors were, anyhow you take the window glass out, cut it down, fabricate some metal to the front and back of the door, to extend to the roof, then hinges it. Then get some of the small shocks from the inside of a sedan trunk. and attach.
Thanks for all you help though. i'm not saying it would be easy, just asking people for IDEAS.
