Intended for compatible 1964–1972 Chevrolet Chevelle applications. Verify the exact model year before ordering because firewall and HVAC details can vary. Intended for small-block engine configurations as listed. Do not assume compatibility with big-block applications. Confirm heater-only versus factory air-conditioning configuration. A/C-equipped cars can use different firewall openings and HVAC housings. Verify heater-core location and inlet/outlet tube orientation. Check blower-motor mounting pattern if the motor is reused. Confirm firewall bolt pattern and seal arrangement. Engine swaps, aftermarket A/C systems, custom firewalls, or shaved engine bays may affect fitment. Chrome plating can slightly change edge thickness, so test fitting before final assembly is recommended. Do not assume heater core, blower motor, seals, or mounting hardware are included. Inspect the firewall and surrounding mounting area for rust or previous repairs before installation.
