John, Thanks for the time you took taking pictures and narrative explaining how to accomplish this task. I found a new complete unit on Ebay for $45.00 with free shipping my car 16 years old I figure it worked well this length of time I'm install the whole thing so I don't have to mess with it for the next 16 years. Last time my thinking was going in this direction some drug addict ran in to back of me while I'm stopped for red light. in vw BUS KILLED HIM. I DROVE MY CAR TO MBZ DEALER ROOF BUCKLED UP 3 S'HORTER THAN WHEN I LEFT HOME.
