So I am in a little trouble with my manual conversion. I sourced a manual 1979 240d at a junk yard a while back and got the trans and flywheel and everything I would need for the swap. Then when I removed my auto from my 1984, I also removed the auto flywheel without marking its location to the crank. I looked over the manual flywheel and I have found what I think its the alignment mark to the 240. I am a little confused as to what I should do now. I dont want to mount it as it is because I tried and had bad vibrations, but not 100% sure it was from the flywheel, but now that I have found this mark, it might be. Since my engine is an 84, shouldnt the auto flexplate be neutrally balanced? So could I just have a shop balance out the manual flywheel and bolt it up in any position? I have thought about match balancing the flywheels but then I still would not know which of the 12 positions to bolt it up. Please, someone help, I am stumped.
