I need to replace my worn AC clutch but I cant figure out what application it was originally from to get the right part number.
I have a good working AC system that I've been running for 13 years now, needs a new clutch.
I bought the motor side of the AC as a complete unit to fit to my HZ, I have no idea what application it came from.
It seems that I have the "long" pump from a 80/100 application with a deep or "short" pulley to line everything up.
There are a lot of OE applications where the pulley is shallow or "long" in order to use the more common "short" pump on the 80/100 trucks.
Good thread with that and other info here:

What I have is:
You can see the pulley is very deep on the sleeve, as opposed to the much more typical HZ/FJ62/Mini Truck pulley here:
And side-by-side here:
This is part number 88410-60310, most typical for HZ trucks and the same dimensionally as the FJ62 which also uses the same dimensional pump that fits the HZ bracket, etc.
Conversely there is also a very common part 88410-22480 which is a crazy shallow ("long") pulley to make the short pump line up the the HD/80/100 crank pulley, thankfully its not that since those are stupid expensive.
What I can't seem to turn up is the deep/short pulley for the long pump like I have. I did look to see if maybe I could bolt a HD pulley on my HZ crank instead but unfortunately they are the same part number- the mount bracket is the difference between needing the "long" or the "short" setup. And the long v short setup really just comes down distance from AC mount bolt to pulley groove, there are multiple combinations to get that to be long or short overall.
Now if I get completely stuck I CAN just mount a 62 compressor and use the 60310 pulley and be good to go- but my AC works well and I don't want to change the pump if I don't have to.
Here you can see a 62 pump, which would be a "short" pump compared to the "long" on my truck:
And again:
So part options that I have explored so far:
Obviously the 88410-60310 since its the most common (and I also pressed the bearing out of that one and used the spline clutch to milk some more life out of what I have)
The 88410-60340 is listed as the HZ clutch for when the AC was a "dealer option" from 93-99, which is promising but I can't find a pic of it, and it maaaaay be a grooved belt pulley as well.
Its counterpart would be 88410-60230 from 90-93, but once again, no visual.
There are two pulleys that are the inverse of what I need, the 88410-22480 mentioned above, and the 88410-35250. Their grooved belt counterpart seems to be 88410-6A010.
The groove belt counterpart to the 88410-60310 is 88410-34040 and interestingly enough there seems to be a groove belt version of what appears to be the correct depth of pulley for my application that is 88410-34020, but when I check the other variations of it's application there are none with the V belt pulley groove.
Looking past Toyota numbers there are a couple of great sources for all variety of the clutch/pulleys, but after scouring these, still nothing that would match my setup. In fact- the majority are pushed the other direction where the pulley is all the way to the front of the vehicle, rather than the back.

So- has anyone seen a setup with this deep pulley that they know the origins of so I can look up the part?
Thanks for the help.

1HZ A/C Compressor Question
I am planning on a 1HZ swap into my 1977 FJ40. I'd like to add A/C to the truck at the same time and I'm researching various setups. I found a photo of a 1HZ swapped FJ40 with a Denso A/C compressor (Model: 10S17C). Rather than using the conventional "manifold" type A/C lines, it uses simple...
