Thanks, guys! Yeah, the front fenders didn't necessarily want to go on straight, but using the hood for a guide was a big help: I taped that down, taped the fenders to it, and glued everything together from the inside. After about a week of letting it set, I went back and filled in the worst of the door seams, cut new ones that followed the lines better, and block sanded everything to level it out.
Sure, which part?
