Yeah you just unscrew the nuts.
My new headlights didn't come with new nuts but when you put the corner lights on
you can use the same ones and they're cut to dig into the corner lights.. post thing.
Lol sorry I don't know any of the terms, but when you get your corner lights they're the
legs sticking out are smooth right? Those bolts that you unscrew from your old corner lights
will cut into the new ones, making it look as if they are screws..
That's the best way I can explain it, sorry I replied late I haven't been on here in a while.
I did the corners and the head lights myself. There is, I beieve 4, 7mm screws that hold the grill in place. It tilts out. The corners are held i place with a plastic nut.
