Has anyone replaced the Kato couplers on thier NW2 switcher I had to remove them to paint the engine and when I reassembled them , well they dont uncouple now blame this on these 61 year old fingers but I am sure i bent the little springs anywho , i want to replace the things with MicroTrains couplers i am thinking the 1016-1 will work but wonder if anyone else has done this. if not with tow 1016-1's but with another one? thanks for the info
