1963-69 1st design (produced before 12/25/1968) Heater fan blower motor resistor mounts into forward side of inner heater box without air conditioning option
1964-65 coupe rear window power vent resistor mounts into blower fan case behind left wheel well inside the car
This Resistor is NOT a "one part fits all applications" product. The blower motor resistor is made to the manuafacture's physical and electrical specifications with the correct resistance necessary to provide accurate and constant blower motor RPMs, as required by the design of the vent system, for optimal and equal air distribution.
