If you are going the show route, keep in mind that this is not a look alike for the 113 cars. I had my clock changed over to quartz by Palo Alto, that way I kept the original face, and the more pointed chrome bezel (not the rounded over one as on the later cars), and it keeps dead on time.
Cost was US$190 plus 10 or so for ship and handle
