Im afraid you are right. But to buy 24 new bolts it will cost some bucks
And I think guys who did conversion used old bolts and still doing well. I think I will use old bolts also just will make sure to use right balance washer (blue dot). And still I need to find somewhere correct torque to bolt them (specifically for M3 E92 side shafts and drive shaft)
