1957-62 Chevy Corvette Cable Driven Windshield Wiper System - Specialty Power Windows

The Specialty Power Windows (SPW) 1957–1962 Chevy Corvette Cable Driven Windshield Wiper System (Part No. WWK-5762V) modernizes the wiper mechanism on solid-axle C1 Corvettes by replacing the factory vacuum or cable-drum wiper setup with a high-torque electric dual-drive assembly. Built specifically for late C1 fiberglass bodies, the kit positions dual cable-driven wiper transmission wheelboxes directly into the factory cowl holes, allowing reuse of original exterior bezels and retaining nuts, while tucking the commercial-duty 2-speed motor under the dash to clear aftermarket steering columns, updated wiring, and modern climate control units.

System Architecture & Engineering Highlights

• Factory Cowl Transmission Alignment: Transmissions mount directly into original 1957–1962 Corvette cowl locations, enabling clean reinstallation of factory-style exterior trim bezels and mounting nuts.

• Under-Dash Remote Drive Motor: Driven by a commercial-duty 2-speed motor generating 300 in-lb of stall torque. Tucking the motor up beneath the fiberglass dashboard eliminates rigid mechanical OEM linkage arms and clears space behind tight instrument clusters.

• Selectable Switch Controls: Available with either a standard 2-speed switch (Off/Low/High) or an upgraded 2-speed intermittent delay switch to tailor dash operation to your preference.

• Adjustable Sweep Geometry: Internal eccentric gear mechanism supports sweep adjustments from 90° to 160° in 10° increments, allowing precise calibration to sweep the low, curved C1 windshield without hitting the lower cowl rubber or A-pillar weatherstripping.

• Standardized 1/2" Shafts & Knurls: Output shafts accept standard 1/2" fine-spline knurl wiper arms or smooth 1/2" diameter clamp-on arms.

Installation & System Notes

• Switch Mounting Location: When selecting the 2-Speed with Delay option, note that the intermittent switch body is larger than the original vacuum/mechanical switch and will not fit in the stock factory dashboard switch hole. A custom dash location or under-dash bracket is required. The standard 2-speed rotary switch mounts more easily in original dash provisions.

• Corvette Windshield Sweep Setup: Configure the motor's internal eccentric sweep adjustment prior to final under-dash installation. A 100° to 110° sweep typically provides optimal glass coverage on the curved 1957–1962 C1 windshield without running the blades off the glass onto the trim.

• Guide Tubing Routing: Route the aluminum guide tubing with smooth, wide bends (minimum 4" to 6" radius) between the motor and both wheelboxes to minimize internal friction and prevent cable binding.

• Cable Lubrication: Coat the entire spiral drive cable generously with waterproof white lithium grease or synthetic silicone lubricant prior to pulling it through the aluminum guide tubing.

• Best Installed During Construction: Recommended for installation during vehicle assembly or interior restoration before installing defroster ducts, instrument clusters, and under-dash upholstery.
