970-1972 Door Glass Track Assembly (Left) (1485ZD)
970-1972 Door Glass Track Assembly (Left) (1485ZD), is a direct-fit reproduction window linkage kit manufactured by Dynacorn. It replaces the rusted, bent, or worn-out lower horizontal window sash channels that connect your door glass to the window regulator arm rollers. This heavy-gauge steel track is vital for eliminating “sloppy” or wobbling window operation.
Key Product Features
- Comprehensive Integration: The assembly provides the structural steel tracking mechanism alongside the specialized rubber cushion liners and crucial glass-retaining mounting stud hardware needed for a complete replacement.
- Corrosion Resistance: Finished in a premium black EDP (Electrophoretic Deposition) coating to defend against moisture accumulation inside the lower door cavity.
- Broad GM A-Body Fitment: While cataloged primarily for the 1970–1972 Chevelle and El Camino, this exact tracking profile also interchanges seamlessly with other 2-door hardtops and convertibles from the same architecture era, including the Monte Carlo, Pontiac GTO/LeMans, Oldsmobile Cutlass/442, and Buick Skylark/GS.
Installation Tip
Before you mount the fresh track to your door glass, avoid applying any grease to the track rails right away. Leaving the channels clean while you align the door glass studs and regulator arm components allows you to blow out lingering metal shavings or debris without creating a sticky paste. Once the track and glass are tracking squarely up and down, pack a premium white lithium grease where the metal channel meets the plastic/nylon roller guides to guarantee smooth, frictionless operation before sealing the door panel back up.
