Would like input on aftermarket bedsides

[Mattchu60]

I got a big dent in one of my bedsides. I am going to be repainting the truck in the future, so I'd like to replace the whole beside with a new one. I've taken them off before and its pretty strait forward, so that doesn't worry me.

Classic Parts carries a long box side for my truck (square hole) for about $400.

I hear that the aftermarket fenders are not great, but haven't heard much about bedsides.

I'd like to hear from anyone that has used an aftermarket bedside, does it fit pretty much like a stock one? The ad says its same thickness and bends as OEM.
