i ahve looked at npd yearone ground up, tamraz. any suggestions before i order?

Buy Goodmark ONLY!!

I know this is late but,,, I purchased dynacon fenders and they suck you will wind up cutting the inner supports and rewelding them. Goodmark doors are 1/4 short they are so light like paper the face is so wavy. Goodmark inner fenders they suck and dont fit get ready to by leather gloves and rubber hammer to rebend them if you can repair what you have do it you will save money and time. Nothing is bolt in. Even the dynacorn hood is not ready to paint they all require extensive work to get it ready the ends are bent to the wrong angle and the metal is so thin it will dent from placing a hot rod mag on it...

Huh,my goodmark front inners dropped right in.

Use original (new or used)GM fenders and doors (and other GM parts) whenever possible!

To answer your question: Use NPD, Ausley's, Year One or TC sponsor, Ground Up. Not knocking the other vendors, just offering up my suggestion based on experience.
