1969 AC with tunnel/no dash ?

[bcfishon]

I was looking over a 69 suburban today with the AC tunnel front to back and under the hood I could see no AC compressor on the motor?. AC components were in the grill area and with my limited viewing I couldn't see any provisions for lines to run to the motor. I am unfamiliar with this particular unit and the rig looked fairly unmolested so I wasn't sure if it was missing the compressor or if its different than your normal Auto AC system.
