Electric Life custom fit power window kit for 1957 through 1960 Ford Pickup Trucks. This kit was designed to work with factory vent windows intact. Kit will not work with one piece glass installed. This is a bolt in kit designed to replace the manual window crank mechanism. Designed specifically for this application, this kit comes with complete with left and right regulator and motor assemblies. This kit does not include switches or wiring. Switch kit must be ordered separately. We highly recommend using the RELAY1 power relay when wiring up the switch kit unless you have installed an aftermarket wiring kit with a power window connection.
