They absolutely do swap.
The late Bill Franke and I went way back - Young Pfoot was my idea - he used to send me his new parts prototypes to field test installation and use.
When he shut down during periods of health crisis, I could still buy the -AK foot from Pure Fishing, along with the graphite-filled drag ratchet plate - I installed those in old Medalists for several folks.
Just don't expect them to be as strong as One Pfoot barstock, because they're die-cast.
Even Martins are on the same centers - but the plate width is different, so they need wider spacers and longer screws.
