I am looking forward to following your thread.
2x4's are definitely cheaper than the steel tubing. That is exactly what I used in my build and it worked out great as I used 1 1/2" x 3" x 3/16" tubing. I also made plywood cutouts of the OD of the tire diameters front and rear and placed them at their respective elevations in relation to my proposed chassis ride height. Mind you, this was all done with the body being there and blocked up on the 2x4 dummy chassis. That way I could stand back and see how everything was going to "profile" which I feel is VERY important in ANY car build.Well i finally have my donor vehicle in the garage. 2005 Silverado. Gonna strip anything remotely useful. Built a frame mock up from 2x4's (great idea from who ever told me) using the Youngs guide. Seems the kick up at the rear seems way to small. Glad its only 2x4s. Lol
I have some pics of in progress but need to figure how to resize so i can post. Will research that later. Problem with being retired is no days off! Lol
