Kinda looks like they were still using the '67-'68 chisel nosed hood too in the ..Nueva Pick-up" spec sheet. I've never seen the rear quarter panel wheel high trim lines before. I think I'd like it on a clean-body panel or sub. I have seen a few Mexican Chevy trucks '73 -later models with '67/'72 style fleetside tail lights. Both in Mexico (Sonora) and Tucson. We see quite a few Sonoran rancheros up here shopping -- especially at the holidays-- newer Mexican Chevy trucks have a grille like a GMC but it has a big Bow Tie in the center instead of the GMC letters.
