HELLO!! I have an 89 GTA with a light gray metallic paint job, I believe. I am going to have it painted and wanted to know how to decipher the paint codes? I could not find a paint tag anywhere on the car... maybe I am just not looking in the right place. Anyways, any help would be appreciated. Also called the dealership and they claim they can only go back to 1990, hence no go for the 89. Thanks
