I have a 2001 Silverado step-side. The truck bed has a wide plastic cap that protects the top of the bed from being scratched. Lately the cap has started warping and lifting away from the body. A few months ago I put a couple of rivets in to pull the warps back down to the body but I'm gettin more lifting still.
I have seen this warping on lots of other short beds and it just looks crappy.
Any advise will be appreciated.
