Did the "K5 Blazer" fender emblem change between 69-72?

[Maximus]

Hi, random question... my K5 fender emblem on the right side is broken. it just says "K/5" and "ER" the center section broke away.



so I have been casually looking for an original replacement fender emblem that has some original patina to blend in with my truck. one finally came up on flebay so I jumped on it, it arrived and now I have a question. My sheetmetal looks to be all original, however there is no center hole drilled on my fender. There is a long living rust pattern on the inner fender and bottom of the front fender from battery decay that makes me think my fender is original, however the new (used) fender emblem I found has three studs on it to attach, one on each and and one in the middle.

Did the '72 blazers only have a 2-stud fender emblem? is my fender just not what it appears to be? I cant see any filler and the faded paint with the greenish primer bleeding through screams originality...
