I guess no one has tried to separate the headlamp from the mounting panel. Today I removed the headlamp and foglamp from the mounting panel of a junk part I had. I sprayed the adjusters and the ball sockets with PB Blaster. I unscrewed the adjusters and popped the balls out of their sockets. I received my replacement headlamp assembly on the 25th.
The mounting panel, foglamp, and headlamp are good, but the panel that is screwed to the headlamp was broken. So, I have to remove parts from my old assembly and install onto the replacement. For $71.00 US I got a good deal.
