I have a BRAND NEW, still in the plastic Zoom Multi-friction clutch set. It has a 10.5" pressure plate diameter and 1-1/16"X10 Disc spline. This will fit many mustangs from 86-98 with a 10.5" clutch. Set includes everything listed on the front of the box, instructions and even the stickers. This set retails for around $260, Jeg's has them for $249 I believe but you're gonna pay more for shipping. I can let it go for $220 plus shipping or come pick it up, I am located in central KY. Here are some pics and a link to the one on Jegs (part # MF48-1):
