I haven't swapped the cover into the car, but with the cap screwed down, it's got full mobility and a nice smooth action. Because of the most slot wear below 3 o'clock and less above 9 o'clock, enlarging & squaring up the slot parallel to it's original orientation, tended to move the whole slot back. When it fit in the slot with the roll pins in place, I was able to establish a shiny wear mark on the rear surface of the brass cup that the ball sits in. I'm going to file a bit more off the front of the slot and it'll be better than new.

Just FYI, the roll pins I found were 3/8" OD, and the ID is almost a perfect match with the pin on the shifter, so it tapped on snug. I put the slot in the roll pin up, but you knew that.

If anybody wants me to cut them up pairs of these roll pin parts, let me know. You'll still have to file out your own cover.
