Make sure your friend knows how to weld, a tig welder works the best. My old toyota has had the bed off 3 times in 6 years, mainly passenger side rail by gas tank 90% plated from shock tower to back cab mount. It is strong. If you fix make sure you cut all the soft metal out go to town and clean it out, shortended up zaw zaw blade worked good for me.Plate it, run it,and beat it. Get to know your local inspection mechanic, some states dont allow plating or repairing, but most reasonable mechancs dont mind hanging that paper.
