Are you talking about the ones that run up along the top of the door frame?
If so, you need to peel the door rubbers back. Inside will be pre-drilled and tapped screw holes. I think that there are about three or four of them along the length.
Your visors should have come with some metal brackets also.
I actually figured it out and the seller is going to check on the brackets for me.. Seller was a guy I used to deal with few years back and we lost contact.. So, it was a good reuniting with seller!
