I'm in the Detroit area and have a '55 C300. I need to know if there is anyone around Detroit capable of fixing my speedometer. The odometer works but the speedometer itself doesn't which leads me to believe that something broke other than the cable. It seems to me that I heard from someone in the area last year who does that kind of repair but I lost the info when my old computer crashed. Also I need to know if there is anyone in the Detroit area who either has replacements or is capable of repairing the master switch on the driver's door for the power windows. The switch currently operates the rear windows and is able to bring up the front window on the passenger side but it won't lower the passenger window and is totally useless with regards to the driver's side window. Any info on these matters would be greatly appreciated. Jerry Browarski
