Hmm Where does the fresh air inlet on the unit? Man that is a big hole. I see sheet metal works in you future. You want a custom dash now you will have a custom fire wall too. Also you might want to go ahead and cut out for the blower motor to be able to be replaced.

Just a crazy thought here. I wonder if it would be easier to cut that area of a xj firewall out and install that in your YJ.Since it is formed for the AC already??

For those who have not figured this out I'm old school but can handle the new too.

The fresh air inlet is all the way to the pass. side, the same as the YJ, but the ducting for the YJ will not work. So I am going to have to design a sheetmetal duct as well.

The hole definitely ended up a lot larger than I expected, but it can all be covered with new sheetmetal. I kinda just kept hacking til it fit.

The XJ firewall might not be a bad idea... I will have to look at one closely

Right now, what will probably be easiest for me is to take good measurements and design a new section of sheetmetal for the fireall. I do not have any real sheetmetal fab tools, so the best way for me to do it is to get it laser cut.

I agree on making the hole big enough to get the blower motor out, I was just happy to see it fit today.

I also tore out all the old hacked wiring, hopefully I will get some time to work on the harness this week.

wow thanks for the pics. that is too much of a misfit for the mods I'm already going to be doing without a major (for me anyway) sheetmetal work.

WOW look at those holes lol.. I wounder if an XJ firewall would work sounds like a good idea. the hard part would be cutting it out at the pick and pull..

I know, and I still need to cut more.... I need some sheetmetal practice anyway haha. It is turning into way more of a project than I planned, but hey, when is anything ever as easy as it seems.

I dont think my saw-z-all battery will last long enough to cut out the XJ firewall at the pick and pull haha, but it is definitely a consideration, especially since I still have no idea how I am going to measure to drill the mounting holes, there is just no good datum point on this thing....

I suppose I will see next weekend...

Get a cheap thing of lipstick in a bright color that contrasts your jeep. Smear it on the ends of the mounting bolts and all you have to do is touch it to the fire wall. When you pull it back down the bolt locations will be marked.

I thought of something like that, I just hope I can muscle the thing up there, and push it into the firewall close to where I want it without moving it and smearing lipstick all over haha.

I think my girlfriend did get bright red lipstick for christmas.... she'll never miss it...

Youngjeeper11,
You might need to make a cardboard mockup of the Heater/AC unit with the bolt holes and pluming cutout's. Can you lower the whole unit until the AC drain is right where the floorboard to firewall meet? This would give you a little more room to make up the fresh air intake.

Ya I will probably end up doing somthing like that.

I do not want to move it any lower because then it starts to get into the passenger foot room, it is already about an inch lower than the stock unit is.

more cutting today. I finally ended up just cutting a big ole' hole to make it easier to fill in later. Working on a sheetmetal design as I post this.

I also mocked up the water valve, but I am not really happy with it.

Last, I mounted my vacuum tank....thing, whatever it is called on the inner pass. fender

O and the lipstick worked great, I drilled the mounting holes as well

De nada. I'm kinda like Cliff Claven (Cheers fame). I'm full of great knowledge, not neccesarily useful knowledge.

now you need to pop out a couple of those HVAC adapter boxes for those of us who HATE sheet metal work.

I see that gives you some more room inside Cool ..... Also is that a mounting point by the fan cutout, just above the cool hose for the fan? If so that would not be hard to to do.

I see that you can still use the battery support bolt holes to remount the battery. Just have to use some sorta spacers. Nice!

Hahaha, well it was useful for me.

Well if I get some interest I can make a few, but its still no easy task haha. This sheetmetal piece is still going to need to be welded in.

But I can easily get a few made if people want them.
