problem with ram 1581 and ram power grip clutch set factory bolts will not go thru pressure plate but fit flywheel ?

picture 1- factory flywheel with bolts for 10 inch clutch aftermarket. ram powergrip clutch bolt pattern will not fit factory flywheel. factory takes 5/16 bolts

picture 2- ram clutch and ram flywheel installed after drilling pressure plate for factory 3/8 pressure plate bolts. ram flywheel takes 3/8 bolts

3- restored every nut and bolt from engine to rearend.

i used this setup so i could install dana 60 3.54 did not trust aftermarket 10 in and china clutch with this setup
everything works perfect ,clutch pedal returns perfect and smooth.
