HW, I used the outermost one, and it sticks out way more than I would like. For now it is acceptable as I was in a hurry to get rid of the claws <g>. I will drill and tap a new hole when converting it to 2R. Amazing how the project list grows!
Clem, the double sided tape sounds like a great idea. I cut the trip pins off of all the Kadees since I do not use the magnetic uncouplers.
