Heater Core Firewall Seal Without A/C 2-1/2″ Thick Heater Core 19641968 GM Models | CHQ Product Offered by AMD
Restore proper firewall sealing and factory-correct HVAC function with this Heater Core Firewall Seal, designed specifically for nonair-conditioned GM vehicles using a 2-1/2 inch thick heater core. This technically correct reproduction is manufactured by Classic Headquarters (CHQ) and offered by Auto Metal Direct (AMD) as a precise replacement for the original GM seal.
Molded from dense, form-fitting foam, this seal accurately replicates the original thickness, shape, and compression characteristics, ensuring a tight seal where the heater core tubes pass through the firewall. Proper sealing helps prevent engine heat, fumes, water intrusion, and air leaks from entering the cabinissues commonly caused by deteriorated or incorrect replacement seals.
