My bet is that the track jack with the longer fingers is the earlier type. The long fingers would be prone to bending and breaking. My money says the short fingers are to reduce the chance of bending the fingers, and the spacer stops the operator from over tensioning the track jack to the point of breaking the fingers. I think the spacer will come pretty close to the distance of a track section.
