So I've just scored on an excellent condition E24 (identical to E28) flywheel to eventually replace the dual mass unit in my '90 535i. The machine shop confirmed that a max. 0.005" cut followed by a surface grind would be all that was necessary to make the clutch face perfect - and that they would remove the dowel pins to restore the proper step down dimension for the pressure plate mounting surface. I can estimate that ledge height with a dial indicator - but if the flywheel had been ground previously, it may be a poor estimate.
Knowing where to find the spec dimension would be nice .... tia
(edit) Also, the starter ring gear has 116 teeth; is that the correct number and profile for the stock 535i starter?
