The 1964-1974 GM Car Small Block Chrome Heater Box Firewall Cover is a custom dress-up piece designed to add a bright, polished finish to your engine bay while providing protection to the heater box assembly. Designed for small block-equipped GM cars without factory air conditioning, this cover installs directly over the firewall-mounted heater box, offering a clean, finished appearance. Crafted from durable stamped steel and finished in show-quality chrome, it combines form and function—making it a popular upgrade for both restorations and custom builds.
Installation:
Difficulty: 2/5 – Simple bolt-on installation using basic tools.
Instructions: Ensure the existing heater box and surrounding firewall area are clean and free of damage. Position the chrome cover over the heater box and align mounting holes. Secure using factory-style hardware or included fasteners. Check fitment and polish as needed for final detailing.
