I know that you can use the e28 flywheel to get rid the dual mass POS, but does anyone know if there are any problems using an e24 flywheel out of a 1986 635? Would i have to use the clutch/presure plate assembly from an e24 or and e28? I know that the flywheels between the e24 and e28 are very slightly different, but does it make a difference? Thanks for all the info, and sorry if i am being redundant. I know this topic has been brought up a few times.
