I had a lot of work done on the cluster:
Install solid state voltage limiter $83.00
Calibrate all gauges $60.00
Convert amp gauge to voltmeter $280.00
Restore tach face and add volt scale to ammeter $145.00
Repair and restore circuit board $65.00
Convert Tachometer to modern internals $320.00
A lot of USD (and even more CAD$$$!!!), but their quality is excellent.
