1973-1987(91) Left Side Air Conditioning Vent

Restore proper airflow and upgrade durability with a premium direct-replacement square A/C vent for classic GM Squarebody trucks.

Designed to replace the factory far-left dash vent, this unit was developed specifically to address the common complaints surrounding brittle, low-quality aftermarket options. Every detail has been improved—from material selection to structural design—resulting in a vent that not only fits like OEM, but performs far better over time.

Manufactured using a more resilient, less brittle plastic, this vent is built to withstand years of use without cracking or breaking. High-stress components have been reinforced with increased thickness, eliminating the weak points found in typical replacements. The internal linkage system has also been completely redesigned with a serviceable plate that allows for full disassembly and rebuildability, giving you long-term serviceability that factory vents never offered.

Each kit includes three felt washers to ensure smooth operation and proper fitment across multiple model years.
