Agree, sounds like; are these the bolts and/or assembly you are referring to?
Note, this is your clutch basket carrier showing the inside facing (transmission side) whereas, if you were to flip this part over - you would be looking at where your clutch pack resides, which also has bolts.
It would probably help us help you further if you explained what you were experiencing and what you've done to locate 6 bolts that require tightening. Ie...did you take your outer primary cover off to reveal these bolts you are talking about. The part description 'Flywheel' used is confusing us (well me at least),
Are you having trouble holding part stationary so that you can tighten said bolts or what?
