I've looked for that gasket for quite a while but never found a source. I think it's 1/2" thick foam, so I wonder if a sheet of open cell foam would do the trick.
I wanted to remove my heater box to paint it but when I found I couldn't get the gasket, I just left it alone. Now that you've brought up the subject, I'll keep an eye on this thread though to see if anyone knows where to find it.
Thanks for replying. I found a company on-line that was selling foam sheets of different thicknesses and densities but I can't for the life of me found them now. I should have bookmarked the page.
There is this place I found, don't know if they have a minimum order or not. I wonder if a yoga mat would be too thick? Or check out the carpet and tile section of some place like home depot or lowes or even children's section of a toy store and see if they might have inexpensive squares like to make a play mat for them to play on or something.
What did you find? If you supplied a link, I can't seem to find it. I think a yoga mat might be too thin and dense, as the original is 1/2" thick and somewhat spongey. I never thought about Home Depot or Lowe's, so that might be worth a look.
Now that was smart!!
I might add if you have a local upholstery fabric and foam place you might find what you need there. I found some barrel clip things for my seats there but they only had a few because the company 'upgraded' to a dif style. They also can probably give you some ideas. Maybe even in a craft store if not needing large pieces.
Thanks for responding Shotrod64, you motivated me into digging some more. I found a company that has all kinds of foam sheets, how well they hold up in an automotive application I don't know.
Cheap enough so might be worth a gamble. Have a look here if interested; Foam Sheet
I'd give it a try. I wish I had done something with mine when i had the heater box out. I was too cheap to buy the foam kit at that time. The foam kit pictures looked like just regular foam that would used to seal windows or door ways in your house to me. I didn't want to pay $50 for the heater box to vent hole either so made one out of a piece of waterbed mattress. Just glued it into a tube and wrapped around the wire loop and glued. It is still holding and it's been approx 15 yrs.
I don't know if it would of helped a whole lot to keep the heat out of the car though. I keep saying i want to add a shutoff valve for the summer time. My friend didn't think to open his valve up this summer and he bout froze his tail off coming over the mountains from yakima to tacoma. It was quite chilly and he had no top as it is a ranchero to convertible clone. He'll know next year when we go to the car show again and won't forget hopefully! I know i was sure glad i put at least one of my jackets on at the foot of the pass! In the summer and 80* and up it's pretty hot with that water still flowing through though!!
Hi guys is there a reason to pull the heater box out unless it or the seal is damaged? Is there anything in the box which should be restored? Im restoring the front end in my 67 and have a very small quarter inch crack in the heater box. I was going to repair it then paint the box in charcoal grey. The seal looks fine. The hardware store has foam rolls which are sticky on one side thats what I would use for a seal.
This is the crack in the heater box probably a little bigger than I thought. Still it shouldn't take much to repair just some 2 pack glue should do the trick.
I decided to pull the heater box anyway since Im painting the firewall/front frame area.
Just finished restoring it.
Looks like I got it back together the correct way.
I ll fit the foam seal when Im ready to put it back on the firewall.
I cleaned the heater box with wax/grease remover as it had oil an contaminates on it from being in the engine bay. Then gave it a good sand with a DA sander using 240g an hand sanded where the DA wouldn't go. Cleaned it all again before priming with etch primer. Gave that a light scuff once dry and hit it with a couple of coats of charcoal paint.
Did the same with the fan motor and heater core cover.
Thought I had the gasket figured but got thinking how crappy that course foam looks sticking out from the edge of the heater box. So thinking about using a finer rubber seal on the outer edge and the foam behind the box where its not seen. Ill get it figured shortly.
I know that the non-A/C heater box for 1965-67 Galaxie's is the same. Can anyone tell me if it is the same for the 1968? Also, if anyone has a picture of a '68 heater box and wouldn't mind posting it, that would be helpful, too.
Just a heads up to anyone looking for 65-68 Galaxie heater box gaskets for both non-AC and AC units. Detroit Muscle Technologies is now offering the heater box gaskets for the engine side firewall.
Jim is a real good guy that's more than willing to help out. I requested a set of gaskets for my '67 and he went out and found a heater box 5 hours from him, drove down to pick it up, did his thing and starting producing the gaskets. They are available on his website as well as at his eBay store.
He also has heater box and other gaskets for other Ford models.
I would consider the foam kit fairly cheap. Cutting foam is a pain its hard to get it straight and neat looking. Priced a piece in my local town for doing the job an one place wanted $70usd for it!
