I'm gonna try to weld in some new cab supports on my truck, still deciding whether to pull the cab off, or drop the gas tanks, and work underneath. Would be easier to be able to roll the cab around to work on it, but I don't have help, it's just me, the truck is currently immobile, and I don't have an overhead crane, so I am thinking just dropping the tanks, jacking the body up in the air, and working on it that way.. Any ideas on how to easily lift a cab off by myself would be helpful tips too.. The big question I have is, I keep thinking about these cab mounting rails, they are welded in place, I will have to grind what is left of the old ones off, and place the new ones in their spot (another reason I like the idea of just lifting the cab straight up, is to be able to line these up as I am working) so, when I grind the old ones off, to bare metal, and place the new one in their spot, I am only really able to weld around the edges.. What do I do about the flat pieces in the middle that will essentially be bare metal sitting against each other? Every thing I think of doesn't seem like it will work to keep this from rusting between there! If I paint, the paint won't let me weld, if I scrape just the weld area, I end up melting the snot out of the paint, and it won't be protecting the metal.. I've thought about just using a ton of bolts, and painting between, then using body adhesive when I put it all together, all slathered in, and the combo of bolts and body adhesive should work to both keep rust out, and hold about as good as welding.. Is this a good idea? I know a lot of modern cars entire body parts are held in place just with the body adhesive alone! Let me know what y'all think of this.
