Duh. Yes. They do telescope. They telescope very easily. The problem is in the normal "parked" position they are very hand to "flip" down. I've tried to lube them six ways from sunday. No affect. Very stiff and sounds like and old hounted house door being opened. Both catches have been pulled out of the headliner because of this. Its not the plastic telescope slide thats the problem. It's whatever is inside the plastic slid sleeve. I'm guessing a steel rod or something.
