Ok... So here is the smoking gun.
Things I overlooked and coming to grips with .......
1. the fidanza wheel is not the same diameter as the stock flywheel. I would say it was 2-3 mm smaller. PLUS from the pic you can see the pin is almost flush whereas the stock flywheel has the 5mm height that AF is referring to.
2. I only looked to make sure the pin lined up. DIDNT CHECK THE FRIGGEN HEIGHT.
3. Now I have to back the pin out or replace it with a longer one..... Thank goodness this can be accessed from the reference sensor hole.
4. LIVE AND LEARN.
