A car like yours you almost would have to build from scratch unless one of the top builders has blueprints made up. all of Bruces points he made are true exspecially about the welding in 1/4 sections and not to overheat it or it will become brittle and the welds will crack. The sfi book is the only way to go for the specs and right tubing you need like zipper said. I feel anonther important thing to a build is the planning of the whole car as to where and how everything will get mounted or you will be wasting time and money adding things then cutting them out to move it. remember to also drill small holes ( I use a 1/8 inch) where you joints meet to relieve pressure built up from the weld exspecially on small pieces out they will blow back.you have to have a place for the gases to go. Clean your joints and intersecting places ( I use a scotch brite ) inside and out and acetone to wipe clean. Good luck in your project.
