I just did a little investigating (was gonna swap w/ Sleeper for his OEM) and found that the part number for pre-'98 Zetecs is different than '98+. I'm thinking that mine isn't a freak (that's my job) but perhaps more pre-'98s have been seen in pics.
Right now I'm pecking through registry profiles to see what I can learn
EDIT: I'm noticing I can't even see the FPR in any of these pics. Even my old, stock pics are the same way. Maybe it's just hard to see
