Surfing the forums or maybe google I recall reading well explained instructions on adusting shifting at the shift lever. It addressed the relationship of the tunnel shift rod to the lever geometry. Can anyone direct me to instructions like this?

You're more likely to get a good answer if you tell us what kind of transmission you have, tail shift or side shift.

Just did this today!! Page #9 on Dr. Evil notes.. Thanks Dr. Evil, works perfectly... Worked it out on 3rd gear.. Be advised to drive on it before you zip it all up.. Sometimes it may seen like you got it sitting in the car and shifting into all gears but drive it too, as to make certain all gears are smooth and silky under load.. twice I thought I had it easily and then first would come up stiffer, redo, ect.. until perfect..
