@Dave NYC Hudson PRR K4 posted:I think that is all answered on the link I posted above with the note "Mike Reagan responds on this topic". Marty E had originally posted that link elsewhere when we had started talking about the couplers. If an answer isn't found there, I don't know.
Are the trucks Mike designed way back in 2016 the trucks we are getting today? I would say no just by scanning all the threads and pics, Mike wasn't around for the new tooling of the Milk cars. Others might have better insight.
