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.

Heater Seal Without Air Kit 1965-1968 is rated out of 5 by 6.
Rated 4 out of 5 by RFBM from Heater Seal Kit - Good Review The seal kit was good although the description didn't alert that some type of adhesive would be needed. I assumed (incorrectly) that each piece would have had "peel and stick" pieces. Thankfully I had a can of spray adhesive in stock. Time will tell if the pieces stay in place. The drawing could have been better detailed as to where some of the pieces fit. Otherwise, the fit was good and product was acceptable.

Rated 4 out of 5 by Neil68stang from Good Kit Working on my original '68 Mustang heater box. The kit had everything I needed including the heater-blower seal (from the heater box to the fire-wall). Everything fit well, however, the instruction diagram was a poor photocopy and was really difficult to read, thank God for Youtube.

Rated 5 out of 5 by jah141 from Heater Seal Kit Good product I have 2 1967 Mustangs did one and I can tell the difference in both air flow and temp. Only improvement would be maybe a peel away self stick on one side would take the install to the next step.

Rated 5 out of 5 by Diggler from Simple & Effective Fix All of my seals were gone or rotted away in my my heater box. This kit restore it back to glory and it was really simple to do. No more weird noises coming from the heater any more!

Rated 5 out of 5 by Eddy from Nice fit! Great kit! If your heater box was as disgusting as mine then you need this kit! (dried out seals, full of mice) Every seal fit nicely
