Description
The Specialty Power Windows (SPW) 1947–1954 Chevy Truck Cable Driven Windshield Wiper System replaces the failure-prone original vacuum or mechanical wiper setup on Chevrolet Advance Design pickups with a modern, high-torque dual electric drive. Engineered specifically for 1947–1954 cabs, the kit mounts two cable-driven wiper transmission wheelboxes directly into the original cowl openings using factory bezels and nuts, tucking the commercial-duty 2-speed motor cleanly out of sight under the dash.
System Architecture & Engineering Highlights
Direct Factory Cowl Mounting: Transmission wheelboxes align precisely with the original 1947–1954 Chevrolet truck cowl holes, allowing reuse of original factory-style bezels and retaining nuts to maintain an authentic exterior appearance.
Under-Dash Remote Drive Motor: Compact, commercial-duty 2-speed motor delivers 300 in-lb of stall torque and tucks high under the dashboard, driving the wiper transmissions via flexible cable guide tubes to avoid interference with aftermarket A/C units or modern steering columns.
Adjustable Sweep Range: Internal eccentric drive mechanism offers sweep settings from 90° to 160° in 10° increments, allowing precise calibration to maximize swept area on the Advance Design split-windshield glass without over-sweeping the center divider or rubber weatherstripping.
Standard 1/2" Knurled Shafts: Heavy-duty output shafts feature standard 1/2" fine-spline knurls (and clamp-on capability for smooth 1/2" shafts) to suit original-style or aftermarket reproduction wiper arms.
Complete Turnkey Package: Bundles the electric motor, both factory-location transmissions, vehicle-matched wiring harness, hardware, and a 2-speed rotary switch configured for Off, Low, High, and automatic self-park.

Installation & System Notes
Sweep Setting for Advance Design Cabs: Set the motor's internal eccentric sweep adjustment prior to final under-dash mounting. For the 1947–1954 two-piece split windshield, a 100° to 110° sweep typically centers the wiper pattern within the glass without contacting the center division bar.
Guide Tubing Routing: Form smooth, wide-radius bends (minimum 4" to 6" radius) in the aluminum guide tubing between the motor and both wheelboxes. Avoid sharp kinks or tight turns to maintain low internal friction on the drive cable.
Cable Lubrication: Coat the flexible spiral drive cable thoroughly with waterproof white lithium grease or synthetic silicone lubricant prior to pulling it through the aluminum guide tubes.
Switch Location: The included 2-speed rotary switch mounts cleanly in the stock dash switch hole, preserving factory dash layout while powering the modern electric drive system.
