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.

I plan on using an original AC dash and not templates because the one I have was cut up by the previous owner for a radio. Do I have to use Vintage Air's vents in the dash or can I use factory GM holes/vents?
