Thank you everyone for your replies, I didn't imagine I'd get this much info! So... The combo hose setup that connects to the compressor for an idi running a 134 setup is Four Seasons part number 55314. It fits perfect with the compressor mounted at a 45 as I learned these trucks do. It's long enough to wrap around behind the engine to the drier/accumulator and the other end is shorter and bent correct to pass above the power steering reservoir then hook onto the new larger condenser. I had a custom line made, #6 at the condenser, #8 spring lock fitting at the evaporator, 26" long. I had them make it a 90 degree at the evaporator as this helped clear the dip stick better in my opinion. I'll find Aggiediesel01's write up on adjusting the low pressure switch I and report back once I can get over to my friends shop for a vacuum and charge. I also have a part number for a four seasons compressor that has the plug in the correct orientation and a 6 rib pulley, I'll find it and add it at the end with a full parts list.
