Ok so I have my 74M folder polymer, what I'm wanting to know is will the metal ones just switch out and work just the same or do I need additional hardware?  Is the tang and trunion the same?

It won't be just a straight swap.  The original trunnion for the polymer stock has different internal dimensions.  Mike@Firing line told me that the angle of the axis pin is slightly different (but not much).  Also, the axis pin itself is of different diameter.  I believe the polymer's original axis pin is the bigger one, so you'll need to put a sleeve in the stock for the smaller pin from the triangle stock to work in.  It is quite workable, though.  Plenty of people have done it.  Kevin_M4 comes to mind as having done quite a bit of work with these stocks.
