Anything from MB won't be a flex fan. The flex fans are aftermarket items with thin metal blades that straighten out as RPM goes up, reducing drag (because it stops pulling air) at high RPM's. They are directly bolted to the drive pulley. I'm almost positive you can't get one to bolt up to an MB easily. At least I hope not. You'd be better off using bailing wire to tie the stock MB fan to the failed clutch, and just try to keep RPM's down (say, under 3500).
