Product Description

Heater Seal Kit for All 1965-1966 Mustangs and 1967-1968 Mustangs Without Air.

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.

Great Fit
Replaced all the seals using 3M weatherstrip adhesive. Seals were all a great fit. The deflector door in the defrost section needs some sort of strip on each side so it doesn't rattle. I cut the extra door seal and attached the strips to both sides of the defrost deflector door and it worked great. Nice not having the heater rattle and blow hot air all the time.

I have owned my Mustang Fastback for 45 years and this is the first time I have worked on the heater. This kit contains everything you need to make the heater perform better than when new. All pieces are made the correct size and easy to to follow instructions

Buy This Kit!
My heater box was noisy and raggedy, I used this kit to rebuild it and it's like new! After 50 years, there were no more seals or gaskets besides the one to the cowl vent. This is a very cost effective way to improve your heating system.

They fit well and were a good addition to the rebuild I did on my heater assembly. They actually fit better than I thought they would so I would recommend them

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.
