I have a Luk set in my jetta now. 210mm full setup for a 95 jetta aaz engine, but it is in the 1.6 that blew up in the jetta of mine. I like it. It has stock feel and the wife could drive it.
I had the clutchnet*still do as they redid my PP* 6 puck sprung hub 210mm in. It wasn't chattery at all. It would just do nothing and then you were moving. Almost a complete on off switch. If you gave it any pedal at take off then it was on/off switch. I drove it like a tractor and just let it idle and let the clutch out. My wife drove it once and couldn't get it. She ripped the front engine mount apart.
I don't think it matters what engine for 2 pins I thought it was more about generation. I thought the 1 pin type was MK3 and under that was the 2 pin type.
