I finally had some time, and cooler weather, where I could test fit some different line options on my 80. Here are the problems we face:
-finding the fittings to be able to build the lines from scratch is cost prohibitive.
-getting the R12 lines new from Toyota is no longer possible.
So here are the two options I can offer:
1) Send me the lines for both an R12 and R134 system and I'll splice (braze) the R134 ends on the R12 lines, add a new Denso drier, o-rings and a new trinary switch to replace the R12 one with specs for R134. Cost for this option is $120. plus freight. You will either need to get a factory bracket or fabricate one to support the drier. This setup is what Kbahus and CycloSteve have for their rigs.
2) Send me your R134 lines, and I use those ends to build a new line from the drier to the condenser. This line is a 1-piece line, rather than a 2-piece like the factory R12 line is. I also build a new section from the switch port to the drier, again using the original R134 fittings. See pictures below and bear in mind I wasn't concerned about making the trial set of lines real pretty. With this setup, you can use the original trinary switch and a 1" shorter drier. You'll need a simple "L" bracket and hose clamp to support the drier. Cost for this option is $189 plus freight and includes the line fabrication, drier and o-rings. A larger than stock battery may not allow enough space for this set-up to fit.
There are bound to be questions, so you can either PM, email or call me (Rex) @ 1-888-438-9534
Option 1 - accomplished ...thanks to Rex
