You can run the factory Denso compressor. Or run a Sanden compressor....http://www.alangrovecomponents.com/LS.htm.
Adapter blocks seem to be hard to find for the Denso lately??

The factory evaporator used a expansion valve/POA valve, To make this work well...You need a NOS/Delco POA valve & R-12.
To use 134a you need to delete the POA valve, Kits available.

I retrofit later Orifice tube/Accumulator evaporator cores in these trucks....77 Olds 98 evaporator cores fit in 69-72 cases.

A Vintage Air A/C/heat kit With a Sanden compressor works really good.
