I have an 84 Mustang GT. Has anybody added the 86 Saleen ground affects kit to it? I was just wondering if it matched up correctly or if there was a lot of fabrication that had to be done.
I don't know the differences between an 84/85/86, but the kits fit right on the cars they are designed for.
Just keep in mind they are urethane not fiberglass so you really can't modify the parts themselves.
So it will most likely come down to an 84 vs 85 factory body, so if they are identical, you should be fine.
