Armada Replacement Pickups?

I recently got an used Armada which I absolutely love. However the previous owner swapped out the bridge pickup and lost the original PU. I called EBMM see about buying a replacement PU but they refused to sell me one unless I sent in the original (which seemed very petty to me). I’m pretty disappointed with EBMM especially since the armada is such a great guitar.

In any case the armada pickup has the 3 screw design like the bass pickups and most standard humbucker are 4 screw and won’t fit the armada. The new Pu in the guitar is just sort of stuck in there. Anyone know of any pickups it’s the 3 screw design that would fit? Anyone have an Armada PU they want to sell? Any help appreciated.
