Frame Boxing

I need to know what gauge metal is the best for boxing in a 03 Sonoma frame. I want to ensure that I use the proper thickness for strength, but the thinnest for the ease of shaping. Thanxs

1/8-3/16 is fine.

ya i used 3/16 i dont think ill have any problems, seems really sturdy

used 1/8 on my s-10. it is the same thinkness as the frame its self

use the thickness of the frame or larger.

1/8".
