Year: 69-70 Condition: NEW Description: 69-70 Autolite Starter Solenoid Application: 1969 Mustang all engines except Boss 429 or 428 S/CJ w/air, 1970 Mustangs except 428 S/CJ and Boss 429 Part #: C7AF-11450-A1 Engineering #: C7AF-11450-A1 Date Code: none Jack’s Comments: This is the most accurate reproduction starter solenoid on the market.The conventional thinking is Ford used the larger heavy Duty starter solenoid for Mustangs equipped with the 428 S/CJ w/o air in 1969.This is not true.Ford used this solenoid for the 428 S/CJ w/o air cars until 1970 when they went with the heavy-duty solenoid.The only cars that came equipped with the heavy-duty solenoids in 1969 were the big block air conditioning cars and the Shelby.A heavy-duty solenoid might have found it’s way onto a 1969 428 S/CJ car when this smaller solenoid failed and the dealer installed a heavy-duty unit.This would explain why they started to install the heavy-duty solenoid on all 428 S/CJ cars in 1970.
