The speedometer kept behaving like crazy. Hot head as I am I bought a used one on ebay. Then, thanks to these great forums, I learn that there is no way to switch them without some programing. Abdi, my mechanic (yes, the very same one that left that the car fell from the lift) recommended me to call Leo’s Speedometer Inc in Meddley, FL. Eddie, the manager, is an intrument cluster master. They work for Florida Highway Patrol and many LE agencies.
