So apparently there are 3 ways to deal with the AC on a 1st generation 4runner conversion:
1) Keep the 2rz/3rz compressor and use the top of a 1988 V6 (3.0) 4runner compressor - I'm told that the factory 4runner AC lines will then adapt to the 2rz/3rz compressor. Convert to R134a. Unconfirmed.
2) Keep the 2rz/3rz compressor and have custom lines built. Convert to R134a.
3) Keep the 22RE 4runner compressor intact. Leave it in the truck when pulling the motor and don't break the seal on the refrigerant.
I chose #3.
Props to liveoak on this forum that pointed out that the compressors will bolt up to either motor, at least in the case of the 4runner... And noting that a 22RE compressor, Chilkat mounts, and 2rz/3rz = clearance issues.
LiveOaks build is here:

To deal with this, you need to "modify" the Chilkat mount, the stock mount cover, and nibble a bit off of the rubber isolator itself... Here is LiveOak's mount:
This is what it ends up looking like - pretty tight.. So I hope you've got a good ratcheting wrench to get at the engine mount on the block... Thanks to Ryan here locally who let me borrow his 22RE compressor to mock this up out of the truck:
