I've been collecting parts for my 85 Jimmy. All the parts are there to put together but I have no idea if it is all going to work since its been open to the elements for so long. I figure there is no harm in replacing the essentials and putting it all back together and having an AC shop put a vacuum on it to see if it will work or not. I figure if I can get by doing that then eventually doing an LS swap will segway into replacing all the OE stuff with a Vintage air setup.
