You don't need any original parts. None.

All you will need for the LS is a compressor mounting bracket, and compressor to fit it and you can connect to the vintage air. My truck was a non-AC truck originally, and I just cut the holes in the dash for the vents, and the VA sits under the dash. VA provides the hole templates and vents. The firewall cleans up nicely too, since the heater box is inside the cab.
