@GO550 Sorry, just saw your photos and you have the early trans and the early throw-out with removable clips (late model have the clips integrated into the bearing housing) so you'll need the early model HD pressure plate. EMPI is a distributor for Sachs and their part number is 32-1235-B Factory part number is 311-141-025EBR I only assume their is a different part number for stock vs. HD but be sure to double check it is HD.
One other small tip is once the throw out is installed put a SMALL dab of high temp silicone on the springs where they insert into the side of the throw out bearing casing. The aftermarket springs aren't shaped as much as the old German OE ones and on occasion can get spit out causing TO bearing failure. A small dab of silicone helps keep them in place.
