Buying all new hinges might get a little expensive so I would just pull em off and paint them if you want flat black. As far as your lights go, I like these brackets
. You could also get some of these
to relocate your mirrors. You could also just fab your own if you've got a welder or a friend with one. Both of these are pretty cheap tho so I would probably just buy them. Let us know what you end up doing!
