Gary, How's the drag car running? I have a Pinto shifter in a T Bucket in the back garage. I can't get under it cuz the cars are packed too tight together. As I recall, I measured the distance the hole in the shift lever arm on the trans moved from detent to detent. Then I checked the Shifter the same way. Can't remember what exactly I did, but I made the two match up . That doesn't mean the arm lengths are the same at the holes where the rod attaches. For instance, if the trans arm rod hole moves 1/2" from detent to detent, I made the rod hole in the shifter in a location where a 1/2" of rod movement moved the shifter from detent to detent. Whew, this is hard to expain in words.
