welcome to the forums, now i have a basic question for you already....I see a few ppl mentioning they own a notch, but my knowledge base isn't with the fox body stangs, what exactly is a notch?
Notchback is a styling term describing a car body style, a variation of three-box styling where the third distinct volume or "box" is less pronounced — especially where the rear deck (third box) is short or where the rear window is upright. Generally, the notchback refers to the distinct angle of the rear window in relation to the vehicle's more horizontal roofline and its rear decklid.
The term is derives from the noun, notch meaning v-cut or indentation — though as a styling term it eludes precise definition and can overlap other styling designations
