I want to change the well worn 22 year old sunvisor's in my 1990 1500 Silverado. LMC has the pair and I have the base brackets which work fine. But how do I remove the worn out visor from the base's, and how do I go about installing the new visor/s on the old base brackets. Thank you.

Come on, Somebody must know how to take apart and install new LCM sunvisors on the old bases?
