I have several Bachmann locos and I want to do some changes to them. Do you provide the different parts that are shipped with different models of the same locomotive, separately? I need a straight stack for 2 of my 2-Truck Shays, Oil Bunker shells for both of them too (they are currently coal loads), and the Snowplow and hardware for it for the K-27. I'm sure there are others who would like to get these items to convert their locos as well.
