I feel like this has been covered for older grilles, but I can't find a definitive answer for this specific variation.
Billet grilles are more than plentiful for 81-87 Pickups, but not so much for the vans. About half of the info I can find says that a 81-87 C10 grille will fit on a 1985 G20 van, and the other half of the info I find says that it will not fit. I do not have a pickup around me that I can measure, so I would like to know from someone with experience will it work or not?
The pictures I find of the pickup grilles look exactly like mine from the van, and the mounting positions even look the same in pictures, but some places are saying that the measurements are different.
