....IF your truck is going to be inside and not caught in bad weather very much then a re-pop would be the way to go.
Classic Truck Parts (the one in Oklahoma) has a sale on right now for a chrome grille with powder coated back bars for $348.
Probably from the same place the others gets theres. Just depends on who you want to do business with.
They even had free shipping through LAST sunday night. Probably not purrrfect but depending on how you gonna use the truck.
The painted ones look good and if yours is as good as you say then I'd paint it....just my opinion.
