I have a 66 mustang , with a 2 speed motor .can any one tell me if there is an after market kit .
to up date the wiper system? or a motor from another car that would adapt ?
Some people use the motor, wiring and switch from an early old truck to get the intermittent wipers. Have a search and you should find the info. Also Newport Wipers sells replacement / updated motors. https://newportwipers.com/product/1964-68-ford-mustang/#wiper-motor
