I got my new headlights and I am tryting to install them. The new lights have some kind of mechanism on the top mount that looks like it helps adjust the beam. That part is not allowing me to screw the light in for some reason. I'm thinking I need to remove that thing and use the stock one from my old lights. Anyone have a trick to get it to work? I just worry that if I try to remove the old ones to use that they will break and I am SOL... Any tips? Thanks guys...
