Just acquired a King Pin myself. Really fun for a simple drop target game. Reviewing the pinrepair.com page on KP restoration, but its still too early to take it out of service for this level of work. The pf needs a good cleaning and it needs a flipper rebuild (need to locate the small flipper parts). I'll likely have to pull the backglass for a triple thick as it has some flaking. But for the time being its getting lots of play.
