1967pontiac

The 66 grills are plastic. The 67 grill are metal (chain mail) looking. Also the backup lights on a 66 are round and towards the ends of the bumper whereas 67's are rectangular and are closer to license plate. There are a bunch more differences too. To many to list here 😁 Pretty decent article of the 66-67 GTOs https://www.hotcars.com/a-detailed-look-back-at-the-1966-1967-pontiac-gto/

My name is Robert. I used to have a 67 GTO convertible. I was 3rd owner. Original owner was a woman. It had A/C, power windows, heck power everything! I bought it when I was 15 years old. I rebuilt it so by the time I turned 16 and got my license, it was ready to go. Well in the early 90's it was totaled. If I knew the what I know now about the availability of parts I would have kept it. To this day I really, really miss that car 😞 Ugh now I wanna cry. Lol
