When the factory AC and heater box assembly is removed for race weight reduction, engine bay clearance, or firewall cleanup, the resulting opening in the firewall is large and irregular. The UMI 3030 provides a clean, properly shaped steel panel that fills and closes this opening for a finished appearance, protects against exhaust heat and fire intrusion into the cabin, and provides a clean mounting surface for aftermarket accessories or a fresh undercoat finish. This is a popular item in drag racing and road racing G-Body builds where removing factory HVAC systems is a standard weight reduction measure.

It is designed to close the opening left in the firewall after the factory AC and heater box assembly is removed, providing a clean finished appearance, fire and heat protection, and a solid mounting surface in the engine bay.\u003c\/p\u003e\n\n\u003cstrong\u003eWhich G-Body vehicles does the 3030 fit?\u003c\/strong\u003e\n\u003cp\u003eThe UMI 3030 fits the 1978-1987 Chevrolet Malibu, Monte Carlo, and El Camino, Oldsmobile Cutlass, and Pontiac Grand Prix. These vehicles share the same GM G-Body platform and firewall dimensions for this era.\u003c\/p\u003e\n\n\u003cstrong\u003eDo I need to remove the AC and heater box before installing the 3030?\u003c\/strong\u003e\n\u003cp\u003eYes. The UMI 3030 is a delete panel designed to fill the opening after the factory AC and heater box assembly is removed from the vehicle. It is not a partial delete or overlay panel. Full HVAC removal is required before the 3030 can be installed.\u003c\/p\u003e\n\n\u003cstrong\u003eIs the UMI 3030 beneficial for street-driven G-Body cars or only race cars?\u003c\/strong\u003e\n\u003cp\u003eThe UMI 3030 is most commonly used on dedicated race builds where HVAC removal is part of a weight reduction and engine bay cleanup program. It can also be used on street-driven restorations where the original heater or AC components are damaged or missing and a clean firewall appearance is desired without reinstalling a complete HVAC system. For a street car that needs heat or AC, removing the HVAC box is not recommended.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes the 3030 require welding to install?\u003c\/strong\u003e\n\u003cp\u003eInstallation method depends on the specific application and builder preference. The 3030 can typically be fastened with provided hardware or rivets for a no-weld installation, or welded in place for a fully finished firewall appearance in show quality or high-end race builds. Confirm with UMI Performance if you have specific installation requirements.\u003c\/p\u003e\n\n\u003cstrong\u003eIs the G-Body AC Heater box delete panel Prop 65 compliant?\u003c\/strong\u003e\n\u003cp\u003eThis product may expose you to chemicals including those listed under California Proposition 65. See the Prop 65 warning at the bottom of this listing for full disclosure details.\u003c\/p\u003e\n\n\u003cstrong\u003eHow much weight does removing the G-Body HVAC system save?\u003c\/strong\u003e\n\u003cp\u003eThe factory G-Body AC and heater box assembly including the blower motor, evaporator, heater core, and associated ducting typically weighs 20 to 30 lbs depending on equipment level. Combined with the associated wiring and underdash components, full HVAC delete on a race G-Body can remove 30 to 40 lbs from the car. The UMI 3030 adds back minimal weight as a simple steel panel.\u003c\/p\u003e\n\n\u003cstrong\u003eWhere is the UMI 3030 manufactured?\u003c\/strong\u003e\n\u003cp\u003eThe UMI 3030 is manufactured in the USA at UMI Performance's facility in Philipsburg, Pennsylvania.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Instructions\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eRemove the AC and heater box assembly from the vehicle following the appropriate factory service manual procedure.
