I can pick up a new Chev 1500 AC Compressor (rotary)and receiver dryer cheap. Can i modify it to work with my 1975 Nippondenso under dash system?
Thanks

I am running the stock dash set up in mine with , the 4.7 ac pump .. wanted the stock look . sacrificed performance for looks .. the 71 dash unit works just like it did in 71 , there are no issues with the cold . it is plenty cold . but it is WAY undersized to cool the inside space of a 55 , not enough coil face surface area combined with poor blower speed ,lack of flow .works fine for one person but sucks for everyone else,. in a restoration it would be ideal . but for my daily driver it is not good . I am looking at the resto mods one to replace it in the future , . i have attempted to fix it to make it modern many times ,my condenser is a dual pass ,the compressor works in the dual ac units of the lx470 so is way overkill , used a modern timed expansion valve , even ran the blower motor at 24v to make it sing .at the end... the inside box just performed up to 1970 standards . works just like it was supposed to in 1970
dual pass from a company in AZ . yes it lines up . i measured and got the biggest one to fit the opening . that was in 2000 .may take a minute to find the part number .. Like Jmac i spent way to long on learning thermal dynamics and expanded theory of design to make it the best it could be

There is a guy in Az building a shorty 40 and he has 2 minivan rear ac units mocked up, if we could fit one in the pass 1/4 that would be great...not that I’m anywhere near doing that.Most modern vehicles with a cabin the size of a 55 have rear AC. Pretty much the only way to really cool rear passengers.

I've been putting a lot of thought into my AC and heater. I've seen some trunk mount universal systems that are AC only, so I'd have to do a stock heater on the dash. I didn't want to mess with wiring two fans to do two separate things, so I went to the local pick-a-part to see if there were any units that looked compact. I was really hoping to do a dual evaporator system for maximum cooling and airflow this time.
While walking through the junkyard, I saw quite a few different dash units, but there were all way too big and complicated for what I wanted. Then it occurred to me.... I needed a factory rear AC/heater unit! It would be a self contained unit that was small and only had one inlet and one outlet.
I went to the Toyota section and saw two 2006 Siennas sitting right next to each other. I peeled back the rear right plastic panel in each one and they both had a compact fan/evaporator/heater unit!!! I knew right when I saw them they were perfect. I pulled them out and happily paid $50 each unit. The aftermarket dual evaporator system I was looking at was $1500, so I felt really good about the purchase. I'm guessing these are much higher quality as well.
The donor vans -
Where I took the unit from (I meant to take a pic of the unit in there, but forgot) -
Plenty of room to mount both units side by side under the rear shelf. I plan on some other wiring, as well as mounting the battery back there as well -
These units are so compact I actually thing they have potential to be mounted to a 40 firewall
Has anyone had luck finding replacement condensers for the factory AC systems? As long as the condenser held up, the rest of the system could be upgraded (hoses, o-rings, dryer, etc..). With a new under dash unit, you’d still need to address all of those components.

Bump for the p/n of the condenser you chose, especially if it is from CoolStream, they likely still carry the same p/n...dual pass from a company in AZ . yes it lines up . i measured and got the biggest one to fit the opening . that was in 2000 .may take a minute to find the part number ..
