i recently did this also but i broke a flywheel bolt off into the crank (DUMBASS MOVE!) well i had no other way to get a bolt of the same length because the bolts that came off of the 240d was an automatic so the bolts were longer so i deceded i could cut a bolt and put a washer on it and we tourqed it and it works fine.i swear to god though i thought i was gona kill myself when i saw that bolt break off. turned out i did a smart thing i lubed up the holes with synthetic to make them easier to come out. and the stub that was sticking out came out like butter.
