I have a 50 Chevy 3100 and am installing a new wiring harness. Well I am ordering parts for the parking lamps and came across a little problem I was hopping someone can help me with. I think I have GMC fenders on my Chevy truck. There are round lamps in the fenders and rectangle lamps in the grill; would it be possible to mount GMC fenders with the round lamps on the truck with the Chevy grill?
