truedog,
took me and 2 buddys all day to install the Heidts system. I would suggest having a proficient welder on hand. Also, read the instructions carefully. I just saw a 67 that all the front end pieces had to be cut out because he measured from the incorrect point on the frame rails aft to the crossmember. The entire front front end was 1 inch back and the fenders wouldn't clear. Its a full day of welding and grinding, and thats with a plasma cutter. The full day was after the engine, tranny, fenders, radiator and everything forward of the firewall had been removed.
