Replacement AC Evaporator Switch and Line?

It was rare for a dealer installed A/C kit(00883-xxxxx) be different than factory installed. When it did happen it was usually limited to just a few parts on the vehicle, not the entire system.

JimKola Thank you for your help because I am doing a lot of guessing of why the factory expansion valve will not fit. Since that will not fit the evaporator I have and rock auto shows a low pressure hose for a dealer installed AC I am thinking that those 2 parts and everything between them could be different than the factory air and everything else could be the same as factory air. What are your thoughts ?

I just rebuilt my entire AC system for 1988 DLX. My expansion valve and evaporator fit perfect. the low pressure switch I bought from O’Reillys. The only difference I saw was the copper tubing on the new expansion valve was longer.
Denso 475-2086 A/C Expansion Valve
Denso 476-0006 A/C Evaporator Core

Unless the vehicle was a SR5 I’d assume any truck a/c unit was dealer installed. Toyota had to pay a fairly high tariff on trucks imported to the USA, so it helped keep the vehicle’s sticker price down by making a/c available as a dealer installed kit.
There were 3-4 private distributers around the USA(down to two today) and they often installed non Toyota “upgrades”, but the Toyota ac kit was so complete and cost effective that I never saw anyone try to make a aftermarket truck kit to compete.
Here’s my best guess on the fit issue. And this is just a guess. But I suspect the new Denso part that is slightly bigger/smaller than the one that is on the vehicle does fit a Toyota, just not a USA one. And Denso’s cross reference data from that era may not be as complete as it needs to be. But this is just a guess. If you saw the thread about O2 sensors you might have seen where my new Denso sensor was bigger than my OEM sensor and wouldn’t fit into the manifold. I tried two different Denso sensors and gave up and put my old one back in.
