1968-1972 El Camino Power Window Kit
The 1968–1972 Chevrolet El Camino Power Window Conversion Kit is a highly popular aftermarket upgrade that replaces the factory manual crank mechanisms with electric power regulators. Because third-generation El Caminos utilize distinct curved glass doors, selecting a model-specific bolt-in regulator kit prevents binding and retains original vehicle geometry without the need for extensive fabrication.

Top Conversion Kit Options
If you are upgrading your classic El Camino, these are the leading premium systems on the market:
Widely regarded by classic car builders as the gold standard for structural integrity.
- Construction: Made from heavy-duty 1018 cold-rolled steel with 4130 heat-treated gear plates to avoid teeth stripping over time.
- Features: Equipped with permanent-lubrication Bronze Oilite® thrust bearings and premium ACI reverse-polarity motors.
- Options: Available with no switches, standard chrome door switches, or “Nu-Crank” switches that let your original manual handle act as the electric trigger.
A universal-to-specific adaptation mechanism rather than a full structural scissored regulator system.
- Mechanism: Rather than unbolting the factory manual scissor arms, this system utilizes high-torque motors that clamp directly onto your existing manual regulator crank spines inside the door panel.
- Aesthetics: Comes standard with striking custom billet aluminum up/down switches for a clean, modified restomod appearance. Available . [1]
- Reverse Polarity Wiring: Modern high-efficiency replacement motors (such as those from Nu-Relics) operate via reverse polarity. Unlike original factory GM motors that ground directly through the metal motor case on the door frame, these systems feed both the power and the ground back through the master switch itself. Swapping the two terminal wires reverses the direction of the motor.
- Door Jumper Conduits: Do not cut corners when running the new wires. You must pull back the door panels and kick panels to drill holes for flexible metal or rubber door conduits. This protects the primary harness from getting pinched or chafed when the heavy El Camino doors open and close.
- Lubrication: Avoid standard white lithium soap grease on the track channels, as it dries out, cakes up, and strains the motors during cold temperatures. Opt instead for modern NLGI Grade 2 high-temperature automotive chassis grease along the roller gear teeth, and apply standard lightweight machine oil directly to the pivot pins.
