Removing the drivers and passengers side windows from the wind wing frames on my 70 bee, I've discovered these thin plastic guides that look like a drinking straw split down the middle. They appear to have had black felt material covering them to help them glide???

Anyone have suggestions on how to correctly referbish or replace with new? Also, the rubber moulding on the top of the wing that meets the corner of the side door glass when the window is rolled completely is cracked. Any advise.
