Sounds like a good machine shop!!
I have a 2wd cossie flywheel in good order despite 200,000K miles, ideally needs a skim, but certainly not bad by any means, just a bit blue, and you can have the friction plate free, all the springs rattle like f**k!!
Pm me if interested, I had another skimmed lightened and balanced for £30 by my machine shop so this is surplus now, nb it went from 8.9KG to 6.6KG in case you're interested, how did they wreck yours, trying to slot it by any chance they don't like this!!
