I currently have my door panels off my 70' Cuda to replace the door glass. I see there are some brackets along the top frame of the door that bolt to the framing and consist of a rubber(?) end and appears to be some sort of guide for the window. Mine are so old I'm not sure if it is hard rubber or rubber covered with felt. The car is fitted with aftermarket power windows. What is the name of these parts? I would like to replace them while the panel is off. I have looked online at several places but can't seem to find them. Thanks in advance.
