F150 mirrors--what about the old holes?

[grebus1]

I’m thinking about going with the F150 mirrors as I can’t see much out of the factory sport mirrors. My problem is that the F150 ones need to mount higher than the sport ones. My body and paint work is already done, any suggestions on what to do with the holes from the sport mirrors? I was thinking of using small plugs and maybe them painting them the body color to hide them.
