Help! I have a newly-purchased 1993 Dodge Colt with auto trans. The plastic output drive gear on the auto tranny that drives the cable to the speedometer has failed. This is a mechanical drive to a mechanical speedo. I cannot find a source for a replacement plastic drive. I tried to order one from a Japanese source, but got a different one that would not work. Can anyone give me a part number or a possible source? Searching wrecking yards has not been successful. I have reached a dead end. Thank you!
