The last part of the system is the lines. I already mentioned that I used hard lines from Vintage Air on the condenser.
The discharge line from the compressor to the condenser required some fabrication. I started with the end of a condenser line from a 2000 Tahoe that picked up from the salvage yard. I bent it up as needed and added a M10 switch port fitting and a weld on bead lock fitting.

The bulkhead fittings on the end of the evap lines exit the cab just above the heater box:
Here's an overall shot of the lines:
