Wow thanks for all the advice guys! So it sounds like I need a new drier, but the old expansion valve may be usable. Will any drier work? Or do I need a specific model that will mount where the old drier mounted and have the right fittings?

Hatzie mentioned a Sanden 508 kit that comes with brackets and fittings to match the factory Harrison fittings. Anyone know where to get that? I googled it and couldnt find it. I don't have the factory mounting brackets.

Somebody mentioned low and high pressure cutoff switches. This is the first I've heard of these. Will they easily wire up with the Sanden 508 compressor, and the factory control panel in the dash?

I'll have to do some thinking on what refrigerant type to use. I was thinking r134, just because thats what my modern vehicles use, but I really don't know the pro's and con's. Anybody have any opinions on this?

I'll have to remove the evaporator from the parts truck and see what work I'll have to do to the firewall in the other truck. I've got a more urgent project I'm working on now, but hopefully I'll get to that in a couple days. Should I make a new thread at that point? Is resurrecting and old thread frowned upon?

Thanks guys!
