The easiest one to find is the 717.411. They are found on the 2.3 8v. Your car being a early m104. It will need a m103 flywheel or a moddied 8v single mass. The 8v has two reference marks the m103 early m104 have 3. No problem for a machine shop. 16v tranny is not the stock one for your car btw. Its the 717.412. 412 is the dual mass short shaft version. The front prop shaft will need to be switched. Its pretty easy actually. Look on 190e revolution. There is a great article about this.
