Just ignore me for the most part, but I THINK you need to find a truck heater box that was orignally equipped without A/C.

you might try a search, there have been a couple of threads on this topic recently. Personally, I pulled all the bolts and studs off both the AC and heat boxes and am still trying to figure out how to get them out... something in the middle of 'em seems to be holding everything together. If I can't figure it out soon, the BFH and crowbar might come out...

i searched, but it returned minimal results, i know its been covered, but its one of those things you just dont click on unless you need to know what their talking about or you can help, and I was neither, lol now i wish i had. Anyway steve sounds right from what i seem to remember reading. Thanks guys

The inner and outer housings that sandwich the firewall are a matched pair. You cannot ditch one and keep the other. You need to either just disconnect the AC and leave the housings, or find a donor truck and swap in all the pieces from a non-ac vehicle. Oh, by the way, if you do switch you'll be patching the firewall in one place and cutting a huge hole in another because the air flow inlet (like 4"x6") from outer to inner box is a different location, as well as the heater core inlet/outlets.

Find a doner vehicle and swap the parts its not all the bad did it on a burb I once had. If you switch from A/C to non you do have to make a plate for the firewall cause they are way different. You need the heater core and everything from the doner vehicle, the switches might not work either so get the ones from the doner. Good luck

I've got the setup your looking for.


Pm me and we can talk more about it.

I've been going through this recently with my AC 87. I believe you just need to modify a non-AC blower box to fit over the hole on an AC truck. The diverter thing shouldn't matter. I'll crawl out to my non-AC 73 later today and see what the hole looks like. I plan on putting its blower box over the hole in my 87. The difference looks like about 5".
