Yeah it'll fit a GT, but the later Gt's had a slightly larger emblem, and the grill was sloped, but the older grills will fit(it'll just look diffrent)... i know the 84- will fit the 84- coupes for sure, not so sure if the ealier ones with the older style headlights, but i think it should fit all the years..

14 bucks is a good price, good luck getting the emblem off of the grill thou
