86 K10 "Karma" - Dont make a purchase under stress!!

[Smallz72project]

First, don't flame me, I made a rushed bad decision under stress. That said:

Background story:
A roommate trying to get on his feet, wrecked his truck, the nice guy I am, I lent him my winter truck to drive (1994 k1500) so he could get job and climbing out of a hole. He drove it for 5 months, until his pregnant wife got homesick and decided they were moving back to N.D. The night before they are leaving to move back, he tells me that out of no where my truck stopped driving. I check it out and find the transmission and transfer case are smoked! The engine needs work as well, radiator is super low but just full of sludge. All this a week before I'm leaving for vacation, and winter fast approaching with now only a lowered 2wd S10 as my means of transportation.

I find an ad for a 1986 K10 lwb that's in great shape body wise, gm crate engine, rebuilt transmission. I try to coordinate with the seller to look at it, turns out he's going to be leaving town soon as well and has a couple different people looking at the truck. The evening before we are both leaving is when we are able to connect, the sun is setting, and I don't have a flashlight. First impression of the truck is its in decent shape for what I can see shy of a few minor issues (so I thought). We make an agreement, I get it for an undisclosed amount, less then he was asking, knowing now though...for way too much.

The next day when its light, I look at the truck again. I realize that I didn't notice that it doesn't have any sun visors (not a big deal I have ones laying around), and that when he arrived and when I drove it he had the windows down and vent windows open, well the driver side vent window is broken off the pivot stud and just hanging from the rivet. The new dash pad isn't attached, its just sitting in place. I'm a little more then annoyed and upset (at myself mainly) at this point. So I decide that I'm going to take the bezel and dash pad out so I can clean up the cluster and put in some LED lights. Its then I notice that there are no ducts going to the A/C vents, and there is some hack wiring done. Its the lack of AC ducting that makes me question and search further. I pull the diverter box/heater core. To my surprise the cab was not an AC cab from the factory. They cut the holes to install the ac components (well some of them), but they didn't do it right. The hole for the non ac that should have been welded shut, is still there.
