The loss of my job it put the kibash on buying all new Kydee couplers for body mount. Need 450 sets. But I have enough Bachmann couplers to re outfit everything that doesn't have them already. So, what is your opinion of these couplers as far as duribility and dependibility? I know they won't be perfect size wise but I'm not a bolt counter anyway. If they would last a few years that would be fine to get through this period. As least while I'm going ster crazy at home until something happens I could be be reworking the trains.
