Anyone know how hard it is to align up the front end of these S13's? Mine was in a small accident some time before I bought it, and it looks like the guy just put all mismatched junkyard parts for the hood, bumper, and fenders. I need to realign them. Mainly, how hard is it to realign the fenders? Hood I can get, bumper, ok. But never messed with the fenders, do they just come off with screws? I dont want to tear it all off and be in WAY over my head, ya know?
