I have a cracked frame which is pretty bad, i'v been driving it for awhile on the street with it cracked I think but its not broken entirely. I don't have a repair kit yet but really need to drive the truck until I get the weld on kit. Could I just clean up as much of the crack as I can without pulling the box and weld it up good until I get the kit? Or would that be a bad idea? Or maybe I can unbolt the box enough and move it enough to get the whole crack welded?
