While doing a clutch replacement, I have removed my flywheel for inspection. What I seem to read is that machining a single-mass flywheel isn't required, but highly recommended, and that machining a dual-mass is a bad idea,, or is impossible.
If I bypass the mechanic and take my flywheel directly to a local machine shop, do I need to give them any specific instructions for machining a flywheel, or machining this particular flywheel?
That's the main question. The secondary question is a sanity check, since I can't find anything absolutely conclusive on telling Flywheels apart. Since I have an 89 325i with a transmission out of a first year 325e, there is certainly a question there. I can say that my flywheel looks like the one on the right, or more like it than the one on the left. This definitively means it's a single mass, right?

Thanks for any machine shop tips!
