I have a RAM flywheel (164) and a RAM power grip clutch (11 inch). I spoke to RAM and they said that unit doesn't require dowel pins and to just use the 5/16 shoulder bolts. Anyone else install one of there and not use dowel pins. I just don't want to run into any vibration issues. There are a lot of holes on this flywheel and I know its universal for a lot of different clutches.
