John Deere STX38 Pulley cover for black deck models.

I have a JD STX 38 that purchased over the winter. The Black deck is fair condition but was missing the pulley cover.
I got a cover. My question is....What hold the cover on? Three bolts with nuts? What size? A picture would do.
JD STX38 5-speed CV 13 21509 SN=27044516 252 Moo stx H301526

Thanks
