Does anyone know where I can get the seal that seals the heater box, cowl side panel, and AC evaporator in the passengers side kick area. It’s shown on page 1A-65 of the chassis service manual. Doesn’t come with any of the heater/AC seal kits and I can’t seem to find one anywhere. Thank you.

Unfortunately not. I have that, as well as a foam gasket that I can use where the heater box mounts to the inside of the firewall. In cars with AC, the heater box extends through the cowl side panel to meet the AC evaporator on the outside of the car.

the gasket that seals the heater box to the side panel and to the evaporator is a wide ‘C’ channel rubber seal that looks like the one in the photo below. Mine was completely missing. There’s about a 3/8” gap between the evaporator housing and the cowl side panel where water can run right in to the car without this seal in place.

Yes it does. This is a photo out of the chassis service manual. Shaded areas show the cross sections of that unique seal. Now that I look at this it’s not just a ‘C’ channel rubber seal. More like a ‘T’ with an extension that stabs out past the cowl side panel to meet the evaporator housing.

Hmm, it is, just not my first choice if a seal is available.
The seal gets installed in the cutout in the body. Then, from the outside of the vehicle, with inner wheel well removed and out of the way, the evaporator housing is slid in to an opening in the front of the passenger side cowl. The seals puts pressure against the evaporator housing, but also overlaps the cutout in the body so that water running down inside the cowl can’t enter the car.
To use putty or a pliable sealer, I’m afraid that when the bond between the sealer and the body breaks down, then water will come right in again.

SFD, you may be on to something with those rubber products. I should spend some time on that site and see what they offer later tonight. I’ll have to get creative as to how to make a seal with the products they have.
I guess I was hoping for a silver bullet in case someone out there had already sourced these seals somewhere or had someone build them.

Really a bastard shape lol! Not only the profile of the seal but also the contour of the opening is not flat. I also need the section that stabs out past the cowl and meets the evaporator to be relatively soft so that evaporator can still slide in and mate to it nicely.
I was so excited to buy an AC car from the US as they are rare in Canada, but it’s sure adding work to my project.

Doesn't look like anyone is reproducing that seal. TC article on this seal
Might want to contact Hinshaw and email them a pic of what you are looking for and maybe someone can locate one for you; used or new.

Is there a source for the big seal in the right kick panel for the evaporator box? I have spent quite a bit of time searching and have so far not found anything. If there is no source what have you done to make a good seal? I have the metal for the original seal. The picture is not of my...
