since we are talking about factory service manuals I'll let you decide.
I was just making sure because I had never seen them on there. But I guess you couldn't just confirm FSM's.
You've never seen what on RA? The FSM's? If you're saying that I gotta guess you haven't looked. If you are saying Haynes or Chilton then yeah I don;t recall seeing those either.
Do they have them all? I don't know.
Do they have the one you need? Go look.
I don't generally bring in irrelevant information, at least not without making a point of point out it's not relevant. The following is mostly not relevant to the OP's question.
The OP asked about a 70 Plymouth FSM, not only does RA have it in paper, they also have the owner's manual and parts manual.

They even have the FSM and owner's manual for my 51, no part manual though.
