Heater Seal Kit for All 1965-1966 Mustangs and 1967-1968 Mustangs Without Air.We recommend installing a new complete heater seal kit when you replace the heater box assembly. Old seals can let air escape from the box which will not flow through the air vents.
This is a complete heater seal kit with everything you need to replace the original seals.
Will fit 1965-1966 Mustangs with air conditioning and with out.

Hey if you are repairing the heater it would be foolish to not install the miscellaneous seals and clamps.
Our 44 year old seals were reduced to dust. This kit fit perfectly and made our heater box function like new!! Highly recommend them.
