1970-1972 Door Glass Track Assembly (Right) (1485ZC)
1970-1972 Door Glass Track Assembly (Right) (1485ZC), is a direct-fit reproduction lower horizontal window sash channel. Manufactured by Dynacorn, this assembly acts as the structural track that connects the bottom edge of your passenger-side door glass to your manual or power window regulator rollers. It is a critical component for stabilizing door glass travel and eliminating shaky or binding window operation.
Key Product Features
- Complete Kit Integration: Includes the heavy-gauge stamped steel mounting track alongside the specialized rubber glass-cushioning liner and necessary glass-attaching stud hardware for a full structural overhaul.
- EDP Protective Finish: Finished with a protective black EDP (Electrophoretic Deposition) coating to shield the underlying raw metal against rust and condensation inside the lower door skin cavity.
- Exact Multi-Vehicle A-Body Fitment: Though categorized primarily for 1970–1972 Chevelles and El Caminos, this part features identical dimensions across all GM 2-door hardtop and convertible A-bodies of this era. It installs seamlessly on the passenger side of the Monte Carlo, Pontiac GTO/LeMans, Oldsmobile Cutlass/442, and Buick Skylark/GS.
Installation Tip
When mocking up your window guts, do not apply grease to the new track rails immediately. Leaving the horizontal channels dry while you slide the assembly into place and align the regulatory arm studs prevents dirt, grinding dust, or old door-cavity debris from sticking inside the track. Once your door glass tracks perfectly square and straight all the way up and down, pack a generous coat of white lithium grease inside the channel where the metal guides meet the plastic regulator roller buttons to guarantee smooth, frictionless operation.
