Hal,
I built my custom round & sq. tube frame "from scratch" to fit one of the few Hi Tech fiberglass bodies made.
It took so damn long to do, I forgot why I decided to do it in the first place.
It came out beautiful, but I traded many months of my life for the result.
also, stainless steel; this is NOT a good choice for an automobile frame.
Because of the high nickel content, it tends to "work harden" as it flexes, particularly near the welds. SS is not really for structure, it's for corrosion and/or high temperature exposure.
Unless you are going to bake cookies on it, a mild steel or chromalloy frame is far superior.
