let us know what you find out, Mercedes put some cheap parts into the crossfire's to keep thier cost down, I wonder if there is any thickness difference?

This car is a mixture of non-OEM and oem Benz parts, so beware. stuff will fail, that's why these cars have no value and aren't worth more than $10,000 US new IMO. cheap *** german bean counters.. arhhh

Oh yeah the c230 flyweel was needed to adapt the AMG motor to the manual trans, I guess the rear crank of the AMG was designed for an auto trans.
