The foam for the evap and core would be a best seller too. Sad that theres at least 3 different variants of that foam.

Are those different than the ones I've made? Do you happen to know what variants are out there?

Yes. It’s the one that goes over the plumbing hole. If you look in the engine bay next to the blower motor where the evap and heater core go into the box, there’s a foam there. 
i don’t know all the variants. Most the variants I have seen are in regards to the clocking of the evap hoses.

Ah you're talking about this one!

 

 

Not gonna lie, I was a bit intimidated by the odd shape of it. I can certainly give it a whack.

[eaglescout526]

Yup that one! 
I think I have that one but I feel I’ve seen them where the orientation of the expansion valve is straight up and down too.

New hvac box seals is next best thing to curing cancer !

I reproduced mine with knives, tears, and maybe some blood, but yours look to be better quality.

Add me to the list of people who would consider purchasing

[Javelinmania]

I would definitely be interested in a set if you begin selling them.  My AC is not working and need to remove the heater box to fix a door that does not open.

[DesertRat1991]

Interested..!  There's a wagon load of reasons  why I haven't ripped apart my dash to install A/C yet, but this would address one of them!  

[derf]

I would be interested as well.

[watchamakalit]

I'd be interested in a set.

[GonzoTheGreat]

If you’re still gauging interested for reproductions, I’ll put my name in. 

[H3ADBANG4L1F3]

I better get this finished for all of y'all! Will be posting updates here as I test and I'll make a thread in the vendor section when I do start selling them.

This one is a doozy! Still in testing phase for this piece, need different thicknesses of foam so I just made a mock up.

Looking good! What about using two pieces of foam and bonding them?

That's the idea!

Dug up these pictures of the gasket on my MJ. Perhaps they may be useful for reference

How close are you to having a set available?

Not that far off! I'll be finishing up the most recent seal and that will complete all of the outer seals. Then I need to do a test fit by putting the heater box back into the truck. If everything fits nice and snug then it's ready. If not, I'll need to do slight modifications and another test fit.

[H3ADBANG4L1F3]

That said, eaglescout526 did mention that there are multiple variants of the evap/expansion valve seal. To make the other variants I'll need a source. I'll make a trip to the junkyard and see if I can find some, but if any of y'all have one that is different get in touch with me and I'll send you a full set of seals if you'll send me the one that I need to make a repro of.

[H3ADBANG4L1F3]

Still waiting on some different foam. In the meantime I made steering column and brake pedal/booster gaskets. Not sure if the one for the pedal/booster goes on the outside of the cab or the inside. I think I saw a photo of a simple square one on the engine bay side someplace. Mine is long gone

[A-man930]

I might have the OE one from my 1990.

I can confirm that there are different evaporator and txv orientations. I'll send some pictures when I get a chance. 

[A-man930]

Here's what I made

That IS different! Interesting.

[H3ADBANG4L1F3]

Did a bit of a test fit today. Everything seems to fit really well, need to make up for a gap on the fresh air intake so I ordered some thicker foam. If that doesn't work I'll have to get a bit more creative.

Just received the other foam as well so I'll be completing the evap seal next week at work.

Blower motor seal looked great on the engine bay side. Will get a more proper test fit after I make the necessary adjustments.

[H3ADBANG4L1F3]

Evap seal is looking very good! Might make a few slight adjustments. Pushed the rubber grommet in a bit too far and messed up the front of it, but it should still work to test the fit. Got in my thicker foam as well, will laser cut some more tomorrow and do another test fit this weekend, this time installing the full dash.
