My rear sill is completly gone destroyed by rust. Hell my whole tub is toasted by rust. I'am not ready to replace it right now, probably just strengthen it up w/ some angle iron and flat bar stock. Tell me what have you done to fix this problem? I know there are kits out there, but I don't want to spend the $$$ to fix it. Can I weld attach apeice of angle iron to some brackets to the rear frame member and then weld angle iron on to them. It will work! Eventually I want to tube my body and get rid of the rear of the tub.
