I'm thinking of buying an '82 pickup, but I really have a thing for the round headlights on the '81 models. Does anyone know if you can swap the round headlights from an 81 into an 82 or 83 1st gen? It looks like you should be able to if you also swap in the front grill. Everything should line up the same, but I'm not sure how it would all attach or clip in. I wouldn't want to do it if it ended up not fitting right or bouncing around. I would want it to be a clean swap. Has anyone done this before?
