My original plan was to fix the pilots and convert to Kadees. There doesn't seem to be anyplace to mount the pilot without seeing the deck pierced' maybe someone has a suggestion. So the coupler went on anyway. The pics show the removal and installation. I used .060 sheet plastic doubled up and screwed back on where the claw mounts on the truck. No cutting on the truck or pilot necessary. If the plastic breaks, easy repair to correct. A couple of washers brought the plastic "tongue" to the correct height. Yes the coupler still pivots with the trucks, all the way down to 48" curves with 50' boxcars with Kadee couplers; i don't have anything smaller and can't answer for that.
A little paint and powders for weathering helped a lot. The test with a "lashup" worked fine.
Sorry about the rotation, have no idea how it happened.
