After removing the grease boot I reinstalled the drag link and measured the space between the ball joint and the tie rod assembly (not square in this pic...). I also measured the link end outer diameter and the height where the original grease seal was pressed. The only dimensions that are important is the overall length, and the fitment to the drag link. OD and ID of the part does not matter.

The drag link now has a very slight wiggle in it, the spacer is about 0.005" short of bottoming which is good enough for me.
Road test: WOW!
Completely different handling! From hard over to hard over there is no sensation of binding, straight line steering wheel wander is GONE. Cornering pucker factor is GONE.
