You guys must have better luck with the u-clips than I do. The originals rust up and break, so then they just spin around and you end up grinding the head off the bolt to get the bed off. Of course that ruins your special factory bolt.
No problem getting the old one off, I took the bolt heads off with a grinder, then after taking the bed off (tractor with forks = easy) cut the shafts with a cutoff wheel.
I went with the Dorman 924-311 Bed Mounting Hardware Kit via Amazon, and it worked... as well as it would have worked on the truck it was intended for anyway. I wrote 3-star Amazon review suggesting that prospective buyers have on hand an M14x2 tap to chase the threads because they're damaged from the factory
I TOTALLY agree!Impact wrenches are awesome; I don't care what anyone says.
