I have a rectangular non-remote outside rearview mirror, casting number C5AB-17743-C which was used on Mustangs over a few years. The mirror body is attached to the base the same way all of the 1960?s Ford cars mirrors were assembled, and probably the 1970?s also. I want to have it chrome plated. I removed the glass, and have tried to pull the ball end stud out of the base, but was unable. I don?t see how to remove the body from the base without doing damage to it. Has anyone ever disassembled any of the old Ford mirrors? Thanks.
