I have the hi side that has the Schrader to the side available I belive. And yes there are a few different brackets and I believe I bought one of the last Denso condensers from Amazon when i did mineIf your 22RE didn't have a compressor bracket mounted, you're going to need to find one from an 80's pickup. I know there were a few different compressors that came on these trucks but both of the 22RE's I've installed A/C on I've used this bracket
It mounts with three M10 X 1.25 X 25 flange bolts that go through the side on the block and four bolts that go through the timing cover. Here are the three bolts on the side:
Here are the four on the front of the timing cover:
Not the best pics but if you line up the three holes on the side of the block you'll see which ones are interfering with the compressor bracket. As the compressor bracket is about another 1/4" thicker on the block you'll need to get longer screws for the timing cover. The ones I used are:
2 M10 X 1.25 X 70 with washer
1 M8 X 1.25 X 45 flange bolt
1 M8 1.25 X 60 flange bolt
It's always a good idea to put a little Toyota FIPG on the threads before putting it through the timing cover to help prevent leaks.
You can then attach the compressor with 4 M8 x 1.25 x 90 bolts with a washer.
Once you have the compressor mounted it's really just following the steps outlined in the original writeup. I was able to get everything installed last night on this rig. Denso condensers are NLA so he sourced an aftermarket which seems to be of decent quality and all the lines and holes lined up pretty closely. It didn't come with the bushings to mount it but I got some M6 bolts with grommets and fender washers to mount it.
You'll notice that the drier in the above picture looks a little crusty, and it's because I didn't install the new one.
The hardest part about this entire job is sourcing the parts needed for it and I ran into a small snafu as the high side manifold was incorrect. The schrader valve goes straight up instead of out in front which interferes with the fitting for the low side line. Long story short, I'm not able to put a charging valve on it to monitor the high side. Luckily we could still charge from the low side port, but he is looking for the right manifold so that it can be done correctly.
Driers aren't supposed to be exposed to air for long periods of time, so until we get the proper manifolds/or the order to screw it and charge it this is where it stands.

Is this the style of top plate that’s needed? I believe I pulled this compressor off of an 1988 22re

It was a struggle getting the 4Runner one for my 1987, should've bought three of them back then just to keep handy.
That's the guy we need!
He might have a line on one but if it falls through I'll get in touch with one of ya!

Circling back to this -
Got the proper manifold in and installed - I am now 0/2 on A/C amplifiers during this job, so once again I bypassed it using a cotter pin in pins 3 & 7. The low pressure switch does work, unlike the first time and it held vacuum well.
Got it charged and this thing is freezing. Another A/C retrofit under my belt. He'll bring the truck back to me this week to button up the VSV stuff but I'm a pretty happy camper.

For some reason I feel like my ac should be colder. I don't think it's cold enough. Any thoughts what it could be?

Are you using a Denso compressor? Both of the systems I've done have been really cold, much colder than any modern A/C system.
Faulty A/C amplifier causing the compressor to kick on less frequently and for shorter periods of time?

Yes its a Denso compressor . The compressor kicks on but when the truck idles it seems to not be cold unless I hold the rpms higher. I
On a side note, thank you so much for doing this thread! If anyone has parts to do this on an '82 as well as help with missing pieces on an '87 4Runner please PM me. Thanks!

Did you use a vacuum pump prior to charging?
Yeah I ran a vacuum and it held for like 4 hours till I took it off
I have parts for 84-89
This thread made me realize I forgot to put my AC drain outside of the cab of the truck when I reinstalled it

Hmm. Maybe a faulty expansion valve that's not opening up all the way? How cold is the line from the compressor to the evaporator? The one on this truck was freezing (as it should be)
Did you clean out all of the lines prior to installing?
Yes I cleaned the lined and that line is cold

You should have cold air at idle regardless, kicking up the rpms will cause the compressor to spin faster and it gets colder.
Start with the basic stuff, make sure the belt isn't slipping on the compressor. If you can get a set of gauges on it watch the high side and make sure the expansion valve is opening properly. You can bypass the amplifier and see if that helps at all.

It's cool during idle but not as cold. I wonder if I didn't put enough r134
Ok so I have a question when I installed ac in my 86 I realized there are at least 2 different brackets and 2 different ac compressors. The one I put on my truck is a denso 471 0133 that has a wider mounting from brackets to compressor. Does anyone know what the other compressor number would be on my old one I can only make out 47200 this is the one with a narrower mounting.
have you looked on Ranshu LLC - Everything Automotive A/C Parts and Accessories - https://www.ranshu.com/ ? you might be able to figure it out from them.
I'll take a look at that
Also look at Rockauto.com.
