2003 Beaver Patriot. I need a source for the ball casting that provides attachment and adjustment between the 3 mirror frame and the bracket. Also the trick to getting into the mirror frame.  Remove the mirror, unscrew the casting from the frame, etc.

If you have the Rmaco, you can buy from them. They will also furnish the directions to disasemble the unit. I broke one of mine a couple of years ago. I sent it back to Ramco and they refurbished it for me for a reasonable price.
