Keep shopping the swap meets at car shows and craigslist. I agree on buying used (rust free of course) GM sheetmetal over the taiwan crap.
Ive wondered about the Goodmark parts for our trucks too Ryoken, In Summit, the doors and fenders are less than half the price than the goodmark metal for the musclecars. Might be the intended customer base too, dude restoring a 70 LS6 Chevelle will be more willing to drop the coin for a $400 door vs a guy doing a 77 Chevy truck.
I had a different 79 K10 before my blue one that was almost all the taiwan stuff, bedsides, doors, fenders, rockers and cab corners. You could see that it was done only a few years before I got it and the thing was almost completly shot. Bottoms of both doors and fenders were rusted through, the bottom of the bedsides behind the rear wheel were rotted out already, the metal was really thin and would dent almost from looking at it. Thickness and quality of the metal is what it is, and I suspect that the prep was far from well done also.
Oh, and the rocker fell out the day I was pulling the engine for my Nova, I go to climb in for something and lightly step on it, and the thing fell off. That truck was a ****box though. lol
