Plastic pieces along top of bed on dcsb 2011

I guess these pieces are pretty much the same on most 2nd gen Taco's, right? The snap fitting on one of mine broke, allowing the wind to get under it at speed, it flipped up and broke off the other day. I've tried to decipher the parts diagrams, but can't be sure what the pictures show is what I need, because the picture doesn't look like it.

Are there any aftermarket pieces available(what is this piece called, anyway? Bed edge cap, bed trim cover, what?) I'm thinking of having a couple of pieces of steel diamond plate cut to fit and bonding them to the top edges of the bed fenders after having them powder coated.

Believe there are other offerings out there but I can’t recall off the top of my head, others will have to chime in.

 

Part # 10?
