TomM 25 Report post Posted June 14, 2018 I have my glovebox out and the controls on the front of the a/c heater box appear to be only partially assembled (front being the interior of the car, immediately behind the glovebox door). In addition there's a large gap at the box/cowl interface. I have the Ford service manuals but I don't see the detail I need to understand what's going on. I've attached a few photos (in poor lighting conditions): 1) There's about a 2" gap between the top of the a/c heater box and the opening in the cowl. Also, there appears to be a screw missing. Is the gasket in one of the photos supposed to fill that gap or should the screw be used to clamp the box to the cowl? There doesn't appear to be much free play in the box that would allow the gap to be eliminated. 2) Another photo shows the front of the box looks like a few pieces are missing or separated or both. Does anyone have a photo of that area? This car has factory a/c. Thanks, Tom Quote Share this post Link to post Share on other sites
bigmal 225 Report post Posted June 14, 2018 The bottom picture shows where the cable for the heater control should attach. The heater box should be close to the cowl. About 1/4, With a foam seal in between. Sounds like some of you mounting screws aren't fitted of the brackets have come adrift. Hope these pictures help.

69ShelbyGT350H 61 Report post Posted June 14, 2018 (edited) After stripping my interior out several years ago, I finally have my A/C Heater box back in. Next is the blower and the ductwork. Lizzard Skin CI was sprayed from the firewall to the rear seat area. Dynamat added from the top of the firewall to the floorboard. The tar and paper sound deadener that I purchased with the ACC carpet is then put down followed by the carpet. The original firewall pad was repaired a bit and installed followed by Pink insulation under the cowl to replace the yellow stuff that FORD put in, and the disintegrated many years ago. Overkill on the insulation? Edited June 15, 2018 by 69ShelbyGT350H Editing error when originally posted Quote Share this post Link to post Share on other sites
69ShelbyGT350H 61 Report post Posted June 14, 2018 I seem to have problems with this forum where when after adding photos if I try to then add text between or elsewhere in the post text seems to disappear and other areas seem to move to other areas of the message.

TomM 25 Report post Posted June 15, 2018 Nice - looks great. I can see that my firewall pad needs replacing - I'm just not up to tackling right now. Quote Share this post Link to post Share on other sites
TomM 25 Report post Posted June 15, 2018 So I purchased this gasket from CJPP, labeled Heater Inlet Gasket. It's about 2" tall. Is this the gasket that goes between the heater/ac and cowl? Quote Share this post Link to post Share on other sites
69ShelbyGT350H 61 Report post Posted June 15, 2018 Looks a little tall. Mine was about 1", has a "D" shape to it. Quote Share this post Link to post Share on other sites
TomM 25 Report post Posted June 16, 2018 Thanks for the pic, I'll have to figure out the correct name for that gasket so I can get one ordered. Thanks, Tom Quote Share this post Link to post Share on other sites

69ShelbyGT350H 61 Report post Posted June 16, 2018 And as in bigmal's lower photo (can't see it in mine), the screw should then hold the AC box up to the cowl via a bracket. I needed assistance getting the upper right bolt through the firewall (Upper left in the photo) I used the repro thin gasket on the inside of the firewall (I think they meant for it to be on the outside) and then the original gasket on the outside followed by the metal plates. I put the original hard rubber gaskets in a pot of boiling water to soften them up them enough to get around the new heater and A/C hoses. They did crack a little more than they were but at least they were still usable. Quote Share this post Link to post Share on other sites
