Spectrum tender ?

I have traded for a very nice Bachmann Spectrum 2-8-0 Consolidation. But it has a medium Vandy tender. The wires come from the Engine (instead of tender?) and plug into the tender. I want to change it to a Spectrum USRA coal/water only tender.?
Has anyone done this? and what would be the PN# for a coal tender? also, has anyone got a USRA tender that they would consider a trade? It is a UP one.
LMK, and thanks
Kevin
