I wound up with 3 heater boxes between CL and swap meets,.I went thru them and got 2 good , functional units from the 3, I mixed and matched the best parts among the 3 and basically had 1 complete heater box worth of parts worthy of garbage can fill among them.
Foam seals (not counting the foam for the recirc door) came from DMT
Foam for recirc door came from McMaster Carr
Reman compressor and clutch/coil came among 2 different sellers on ebay
As did new hard lines, a new expansion valve from 2 more different sellers
Dash vents, an instrument cluster bezel, and mount brackets for a factory ac pump came from a junkyard
I also wound up with 2, factory ac dashes and almost 3 sets of the plastic tubes to connect the heater/ac box
to the various dash vents from a swap meet
Though, now that I see the factory ac dash stacked on the bench among the original non ac dash, I can see how easy it will be to cut-in the holes for the louvered vents on either side of the glove box into the original dash out of the truck// so I don't have to worry about finding the (unobtanium) correct rosette rivets to transfer my vin tag to one of my replacement dashes.
I also have what is supposed to be a good used set of V8 hard lines here that I won't be using because they won't fit my /6. And after I bought my reman compressor I thought I saw a used compressor in the attic left over from a truck my son had that he parted out years ago..... If you're sorta close to Chicago I wonder if any of the leftovers might help ya out?
I'm almost there, still lacking a condenser and a couple of smaller more trivial pieces such as a low pressure cutout switch but I have time, as in other stuff I have to do to the truck (that has little to do with HVAC install) before I put it back together
