OK, So I trimmed my fenders to put the 1 piece headlights into my car. Only thing these were given to me by a buddy of mine, and both to the mounting tabs up top are broken. I know you have buy the repair kit from ecs tuning. But I was wondering how these worked? Do they glue on? If the do can't I just cut the ones from the old ones and use those? Or do those screw on... Has anyone used these before and how sterdy do the come out?
