66fs: you wrote "The 1/4 in holes in the 1st and 2nd lever and the 3rd and 4th lever are not the index features. They can not align with the rear 1/4 in hole in the housing" I don't quite understand why you state that. When the 1/4" drill is inserted into the 1-2,3-4 shifter levers, to the hole in back, (R lever pulled back out of the way) the levers DO align properly with the reference tabs, I just did this on mine to confirm. Why do you say that the hole is not a valid index reference?
