You may have to join one of the historical societies and get a member to print off some special ones. I had the same issue, only building a pair of Bowser 2-10-2's into S class engines. I whined to the N&W historical society, and "THE" Ed King gave me 3 sets! I have the details on the boilers and such, but I still need to add the DCC harness. I hard wire mine into place and have a semi-permanent drawbar between the engine and tender. I don't have micro-plug issues.
