I'm very interested, but I'm trying to finish up the other projects on the car first. I'm looking at possibly a late winter/early spring timeframe. The problem I see with this is having to evacuate, disassemble and ship you the parts to be modified. I think I have a spare condenser, but I'd still have to take the lines off my car for modification.
Speaking of the lines - when you modify them, are you replacing or splicing the hoses to lengthen them?

My plan with these is to have a sort of core exchange, where I send the new condenser/hoses to the customer and then get their original ones back to modify for the next person and so on...so if I get through my current pile of interest and have parts left, which I think I should, then I could have one ready for you whenever you are.

Isn't one of the lines that needs modified have the high/low pressure sensors in them? If it's the one I'm thinking of, there's at least two different versions. I had to convert to the one that had a single sensor in it to be compatible with the new engine bay wiring harness I installed. My old line had two separate sensors.

Late cars have two sensors on the condenser->dryer line, early only has the one pressure switch. Like I said, if you cut the ferrule carefully you can salvage that sensor fitting and fit a new ferrule.

They changed the Turbo cars sometime in 1987 to a single sensor with a round 4-pin connector. The original one on my '87 and the '86 parts car had two sensors.

Hmmmm, i may need to look into this with new motor, is the ac system the same on the post 85.5 cars as the pre 85.5?, i have an upgraded altinator so im guessing my motor is an 85.5+? Would it be easier to delete the AC?

AC system is different between early and late. But, you can swap the compressors/lines between years to match whatever the car had originally. The bracket and such all bolt on. Do you have an early or late car? The condensers mount differently between years but I can make it fit your car no problem.

Bump for this - fairly soon there will be a regulatory shift regarding R134 - it is not going to be offered anymore in new cars as a new replacement freon, 1234YF, will be phased in. It will likely be a similar situation to R12 - no longer produced, only available with what is recoverable by shops.
1234YF is a very different chemical from R-12 or R134a though - the pressures are much higher, and the chemical itself is much harder on parts. You cannot retrofit a R12/134 system to use 1234YF.
Time is running out to update your system to R134 if you haven't already...and I'm here to help

I have a feeling that Germany and many firefighters might not be too eager to see the switch to HFO-1234yf. I suspect R-134 will be around for along time. Hydrogen flouride gas is nothing to mess with.
