One of our 1991 mirrors had frozen set screws. If Kroil won't loosen it, don't twist so hard as to break an allen wrench off in the set screw!
Just simply drill the set screw out with a 1/4" bit, and then drill the hole with a 5/16" bit and retap the hole with a 3/8 x 16NC tap. Then remember to use
anti-seize on the new set screws. Ramco still sells the mirror bushings, but have upgraded them to aluminum from plastic.
On a newer coach, I'd suggest spraying with a penetrate, then remove and coat set screws with anti-seize before they become too corroded to
be adjusted.
