Hello everybody! I recently bought a 1981-1982 grille for my 84' on Facebook marketplace. The neat thing about it was the blue bowtie. I didn't think much of it, and then tried to find a picture online of an 81-82 grille with a blue bowtie, and came up short of finding anything. I asked the owner about it and he said it was on his dads truck from the factory. Just looking for an answer here, is it a factory option or dealership option? Thanks!
