5/16-18.

5/16 with 18 per inch but remember that they are grade 8 and not hardware store bolts. You can always order a bolt pack per application from Ft. Wayne Clutch in Ft. wayne, Indiania, U.S.A.

I always go to the parts store and get actual pressure plate bolts. They have the correct shoulder on them so each bolt is centered in the p/p bolt hole and that keeps the pressure plate where it is supposed to be.

OK up date my fly wheel is hosed machine shop says the bolt holes have been plugged as in a bolt screwed in to the orriginal bad holes and machined off redrilled & threaded and then stripped out again.But they had a good used one all ready to go for $110 with all the new grade 8 bolts They changed out the starter gear off the old bad one and pressed it on too.

Flywheel to crank 75 to 85 Lbs. Plate to flywheel 12 to 15 LBS. These are per my trusty factory Shop Manual.

Machine shop should be able to redrill and tap the P/P holes at another location on the flywheel.

Reason I did not redrill is the shop showed me too many defects such as heat cracks already been resurfaced at least once let alone the botched up holes and they charge $85 per hour to relocate and drill & tap holes I got a whole resurfaced flywheel with new bolt sets changed my starter gear out the door for $110

Make sure the bolts are not too long, or the engine will not turn.

It is what FORD called from in the original Factory manuals, so i go with what FORD says.
