| If my memory is correct the Trans Am guys went with rectangular tube for the majority of the spaceframe for both strength & ease of fitting internal panelwork, much the same as the 40 kits. They still used round tube for the rollover & side intrusion bars as these had to be bent without deformation beyond certain limits. Also back around 1984 I can remember a lot of publicity about a spaceframe kit for a Corvette of that era that used stainless round tube with some clever aerospace tech fittings that the s/s tube was a push fit into. These were used @ the tube clusters & the stainless was either brazed or welded into the fitting. I think ' Mr Gasket'?? or a Company similar was behind it. Might be worth looking into if your serious about stainless. |
