Yeah, I've since, searched google for them and I don't think he has enough frame for those. Well.. at least not that second pic.
I'm sure it can be done but in the end you'll just be building/welding a rectangle anyway. I fixed a rusted out toyota frame once and pretty much used angle iron on all for corners to basically re construct the frame. Had the customer paid me more.. I would have bought C channel (factory frame was C) or rect. stock to do it right.
Good luck on what ever path you choose. Best bet would be to buy another frame and if he doesnt want to rip the tub off for a complete frame swap.. section it.
