Hey FF4312,
Can't help you on the shifting (although I have replaced my clutch hydraulics) but I migh tbe able to help you with the FASD.. Mine wasn't working either, but I called Woodie at the Wedge Shop and he told me how to fix mine.. Amazingly enough I was able to fix it - and I ain't no mechanic.. If I can do it - anyone can..
So, I made a small little course to help people understand and hopefully help fix their FASD's as well.. If yours was like mine, it just got gunked up over the years and the linkage might have gotten out of alignment.. Anyways, I've had maybe 10 people email me from all over the world to tell me they got their fixed.
Here's the course online - its Flash, so you might need the Flash player if it doesn't show up. Holler if you have any questions..
good luck -
Steve
