I used 0.120 wall and made the depth to match the existing chassis..you can taper the ends to make it look good..

I have to ask, is this frame REALLY rusted too bad to save? Many times frames will have some severe rust in a rust prone area and the rest of it is still good. It may be "rusted" but it isn't too bad other than a few spots. Just how bad is the frame?

Last frame I built was out of 4130 seamless steel tubing, 5/8" OD, with .035 wall thickness. the finished product weighed about 1100 pounds complete with 150 hp engine. It would carry 40 gallons of gas, and 760 pounds of people and stuff, at about 145mph. and get around 20mpg.
Oh, nevermind, wrong forum.

2"x3" or 2"x4" box tubing, with .125" thickness is pretty std. for a frame. No reason it needs to be different size for different parts, other than narrowing it at the front for asthetics.
