I finished drilling and tapping. She bolted right up. The Pressure plate came from O'Reilly's, probably from China I suppose. It's bolt holes were not oversize to accommodate the bolts with the shoulder so I drilled and tapped for 5/16-18 only and I'm going to use grade 8 bolts and lock washers. will it vibrate?? guess I'll find out, at least I have some kind of clutch to put back in the thing.
