Actually it's from very early Passat3. It also comes with a boot and two bolts.
Needs the bracket that holds the cable in place at the front, too.
This set up was also used in various SEATs - Ibiza and Toledo.
As you want all this to convert to cable you've bought the wrong car - Ibiza or Toledo ABF would have been much more sensible.
You also (obviously) need the right cable to go with it, as it's at a further 90 degrees around to the rod-change box.
Not sure the Toledo cable will be right, as the pedal box on the G3 is quite different to the G2.
Not sure Brad's left leg will be strong enough on an uprated 228mm clutch with a cable clutch though.
