Fiberglass parts

[Red_ver_2]

OK, due to my inability to access any Chevrolets, I need some help. I've been looking at fiberglass body parts for my truck for when I get back to the states. I really like Hannemann because of their rep, but the only bedsides they make for DRW Chevys is for 2005+ trucks. Can anyone tell me, what is the major difference in boxes between my '03 and an '05? From pictures I've been looking at, the taillight looks different, sometimes. If it's close, I can make it fit. It's fiberglass, after all...............


Right?

I think the beds would be really similar aside from the tails, I think they are identical.
