Glad you like my "Big Bolt" grille. See, I learning the lingo!! As I remember, I only had to drill two holes and it bolted right up and fit the opening just fine. But wasn't room for the "Chevrolet" script. It is my understanding that that grille was used in the 1964-66 60 Series trucks. Only problem so far is that the front end of my truck is lowered about 2.5 inches and I can't crank the headlights up enough to see down the road very far!! Don't know if this is allowed but I have an extra one.
