Wiw: 72 gmc lwb 2wd

[71stub]

Since this summer i have wanted to convert my 71 shortbox to include factory air. I realize i will be much further ahead if i just buy a complete A/C parts truck instead of trying to piece everything together. I found this 72 GMC 2WD longbox with factory air. Its a 350 auto that runs but the tranny slips he says. It has ps and pb and comes with a set of rallys. He says its complete but needs some body and mechanical work. It will limp onto a trailer but needs attention. It needs cab corners and rockers for sure and he was going to check out the floors and supports for me. Whats a truck like this worth? Like i said i mainly want to use it for the A/C swap and either part or sell the rest. Thanks.
