I'd like to keep my 97 cobra convertible original, and some of my buttons are faded or worn, especially the volume up down on the mach 460. Any Ideas on where to get replacement buttons, how they come off or how to paint with vynly paint and get the symbols back to original appearance? Also has anyone fixed the auxillary power cover just in front of the shifter, so that it will stay up? Is there a spring or something that would normally hold it up?
