Hi Bach-Man,

I have the Empire builder 4-8-4 set and have been enjoying it since XMAS.  I have since bought some additional vintage Bachmann rolling stock w/ the old rapido couplers.  I understand you can convert them over to the newer knuckle type.  I would like to do that, but need help finding the new knuckle couplers, and instructions on how to do it.  Any advice is helpful.

Thanks, dieselkid
