After a long hibernation, I plugged my original, as supplied, AM/FM single speaker mono radio in and everything works as you would expect for a nearly 50 year old radio. I don't want to do any type of upgrade to the unit, but I would like to change out the radio dial lens. I see Trim Parts sells the replacement lens, but I can't figure out how to get the old one out. There appears to be four spring clips holding the lens in. Removing these loosens the lens, but there isn't enough room to slide the old one out and I don't want to break anything in the process. Does anyone know the trick to removing the lens? Thank you.
