Ghostrider is correct, there's a few excellent books on building chassis and frames. Without trying to adverise I got a great book from Amazon called How to build Hot Rod Chassis and is an excellent book on frame building from the ground up. Regretfully though most of the frame parts are prefabricated so to find parts for the burb might be difficult and you might have to start from scratch.Big thing in welding frames is safety and good welds.
