69/70 Sub questions/ parting out

[ltitsnw]

Hello....I looked at a Sub yesterday, buying for the front clip and tub(looking at trying to crew cab it), this thing has roof air but nothing in the dash, was that how the Burbs were cooled??...the compressor and hoses were still there.....all the interior is there and looks real nice, the front seat and back seat looked almost perfect, the mice had taken over the middle seat......the rear is hatch and tailgate, pretty rusty.........Just trying to figure out about the air, if it's original and if anyone out there would be interested in some pieces.....I'll probably try to get it picked up in the next week......Thanks Troy
