Sorry if posted in wrong section
I have a84 GT that I purchased new. It has the same rear spoiler as 79 through 83. All the other 84's I've seen have the same as the 85 and later the 86 with the third brake light.I have two brochures for the 1984 mustang.One shows the rear spoiler that is on mine and the other shows the 85 style spoiler. Anyone know when the change occurred? How about numbers produced before the change?
Thank You
