We are planning on starting to build the NS 34 Geometry Slug. Does anyone have any recommendations for an older Athearn Bluebox chassis to use? Would an SD7/9 work for a decent replica for the shell? We will gut the loco, so internal space is not a problem as it will only have lights. Also, if anyone has an Sd7/9, are the fuel tanks one piece? I will have to use one, as the prototype has only one. We were also considering using a bluebox SD40 unit if we can’t find a full sd7/9.
