SD 40-3MR

[nhjj4]

  Hello kid's,

    I am working on a small project. Want to make a copy of a Portland & Western SD 40-3MR. City of Salem # 3300
 The unit in question started out as a C & S SD 40 # 880  Well at some point in her life she was modernized.  12" to 1' Kit Bash
She got a smaller fuel tank, Dash 3 electronics, AND !! Dash 2 truck's ( reason for smaller fuel tank )
  I found an Athearn RTR SD 40 undec and started to look for parts. I got dash 2 side frames  Was told they fit BUT they don't fit the stock SD 40 truck. Have new Fuel tank's & PSC hand rail kit's for this and others.
 Will a newer set of 40-2 truck's fit the SD 40 frame ? Just about have all the parts I need as of now. just don't want to start till I get all the parts I need. And Athearn didn't have an answer they don't know?? or won't say.
 Thank's

 Jim

I am probably being a bit silly since it's been years since you posted this. But I can answer your question in short if you're using an older Blue Box model the trucks won't interchange. But the newer ready to roll I believe can be interchanged good luck with your project since it hasn't been posted on fairly certain that it was never completed
