Can anyone tell me besides the grill color, what distinguishes or what are differences in 66 and 67 goats?

Chrome rocker trim from the side view.  66/back is under the door, 67 trim is wider and is on the door bottom.  Tail lights  66 has 3 long slots, 67 has 4 rectangles.

.

 

67 was the 1st year to offer the hood tach as well.  Interior wise, 67 also offered the His/Hers HURST console shifter. With Walnut trim, 66 had a lighter wood trim.   Stiching in the seats makes them year unique as well.

Thank you JUSTA6

The rear I was aware of but not the rocker trim.. very cool, also I didn't know about the hood tach.

Thanks for the info!

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/

The 389 CID engine with three two bbl. Carburetors was discontinued at the end of the 1966 model year...All 1967 GTOs were equipped with the 400 CID engine and a single 4bbl. Carburetor...and could NOT be ordered from the factory with multiple Carburetors....

Also starting in 1967 All GM cars came from the factory with a Dual circuit Brake Master Cylinder (separate reservoir for the front and rear brakes)... And collapsible Steering columns...
