I have several Bachmann Spectrum heavyweight passenger cars with the body mounted couplers that swing with the trucks. The problem is...they SAG so much that they won't couple or stay coupled with other cars...there is a lot of "play" or wobble in them. The cars are lighted with interiors and I haven't found out how to take them apart and I don't want to ruin them. Is there some sort of "quick fix" for the couplers to stop the wobble/sag? Or any suggestions on how to open them up?:confused:

Thanks for any suggestions.
