i just don't understand what's so bad about it?
There are a couple of really big items to consider. First, a C-60 was a commercial truck, not a pickup, so parts are going to be scarce and expensive. There's no sense stacking the deck against yourself by buying a non-running junkyard dawg that's had expensive parts scavenged off of it. Second, just why was it scrapped in the first place? If you discover there's major damage to the running gear, transmission or rear end for instance, you could get into twice your initial cost with the purchase of one item. The brake system will have to get a total overhaul, as those parts deteriorate rapidly from non-use. I'm very concerned about the 2-speed rear axle shifter being missing- - - -junk yard operators don't allow pieces like that to be scavenged off a good, serviceable item, so you'd better count on having major rear end problems. The cab is trashed- - - -a real rust bucket, and swapping to another cab is a huge effort.
After you get it fully restored, what do you intend to do with it? It's expensive to license, and just buying tires will be a major expense. Do you have a commercial use for a 2-axle tractor without a 5th. wheel? About all it would be good for would be as a mobile home transporter, or something similar, unless you equip it to haul semitrailers again, which was probably its original purpose. Without air brakes, even if it was equipped for a semitrailer, its use would be limited. Us mechanics are eternal optimists, but we usually try to heal the sick, not raise the dead!
