Do aftermarket body parts fit OK or will they have weird gaps after install? Are aftermarket body parts really flimsy and if so, does it matter? I'm ordering front fenders and hood Monday and if aftermarket doesn't suck then it'll save some money. But if OEM is the only way to go, then I'll happily do that. I primarily use the truck as a ski truck, so don't intend to trash the body in the course of having fun... only saving my a$$ if need be TIA!
