most imports, it’s either 1.25mm pitch or 1.50mm pitch. If you have one of the bolts out just take it to any hardware store and match it up. If it’s a weird thread pitch, hit up Fastenall or North State Industrial and they will have it. ---

if its a pressure plate bolt its probably 8x1.25, the crank bolts are usually 10X1.25 which is an odd one ---

I suppose I could get you an answer tomorrow…if you want I have spare clutch hardware…and as far as the size…the pressure plate bolts are a 12 point 10mm head, and the flywheel bolts are a 12 point 17mm. my guess on the size before I actually measure would be 8mm X 1.25 pitch.
