I know about the outside screw but the inside bolt/screw is weird so if anybody knows what tool to use it would be great thanks.

11 milimeter or 7/16 inch deep socket with a universal joint and extension

what he said

also to make it a lil easier you can take the headlight out and that will let you get your hands and ratchet in w/o a universal
