Horn button and horn trim compatibility, need some help

If I had a horn trim for a standard 67 steering wheel could I swap this 1968-1969 horn button over to the 67 trim using the hardware and mounting for the 67 button? Was there a difference between the mounting hardware of the horn buttons between the different years that would prevent it from swapping over? I'm asking because I have an offer for a 67 trim for sale to build a new steering wheel for my Dart, but I want to install it with this button instead. I need some advice to know if it will fit or requires different mounting hardware, thank you.

This is the 67 trim I am looking at buying and also the button if this helps, I'm just not sure how the button mounts so I cant say if there is something missing.
