I’m trying to locate a 73-76 a body heater box seal ring. It’s the metal ring that seals the heater box motor to the firewall. It seems like every heater box for sale on here doesn’t come with the ring that goes on the outside on the firewall that seals the fan motor to the firewall. I purchased a heater box but I can’t find a seal for it. Does anyone have one out there they could sell me?
