Scott Mockry has them:

And so does eBay, at *rock bottom prices* caveat emptor, yadda yadda:

This sensor comes in 3 wire and 4 wire versions, but both effectively work
the same and are interchangeable.  The 4-wire version is NLA according to
SJM.  You can read about the differences here, but apparently the 3 wire
version eliminates the +12v wire as not needed, but otherwise is a direct
replacement:

(And no, I'm not shilling for SJM or eBay, it was just an appropriate
question.  Occasionally interesting parts come up on eBay.  I do a search
once a week.)
