From what you can see, does it look like it will take much to get her started? Clean fuel tank, lines, pump, carb, spark plugs, battery, ect. I'm just a jeep guy, but to me it looks like getting her started will be a peice of cake! Whats up with the bed, that isn't original is it?
OK... I admire your enthusiasm, you sound a lot like me when it comes to buying old iron. I jump in with both feet and go thru a rig.
Its funny how everyone says to Jump on it... Unless you have the space to work on, the bigger tools to work with, and a large budget to rebuild it with, do some long hard thinking on it.
But, step back and think about a few things:
First, I would not assume anything with the condition of ANYTHING.. Yea, you might get it started easily, but how well of a condition is this engine? Drivetrain? If you do get it running, PLEASE, for safety sake, dont attempt to DRIVE IT HOME.
It may look good, but trust me, you will end up addressing just about every major component before you will feel it is "road worthy " Brakes ? Tires? driveline?
As far as an offer, I would make a condition up front with the owner that the deal (that you make) holds true ONLY once ya get it running so you can see the condition of the truck.
Trust me, these trucks are NOT cheap to restore in comparision to rebuilding a jeep.
Try 75 bucks apiece for brake cylinders, for instance.
Its a heavy truck, with winch and dump assembly, your pushing 9K in weight.
Dont even think or trailering unless you got a 3/4 ton or larger truck, with desial engine (preferably) and a stout trailer to handle that weight.
Otherwise, you need to make it road worthy enough to tackle the roads and distances to which you want to take it. Breakdowns far from home can be costly.
Am I being a kill joy here? Nope. Just being realistic. Please take this sound advice from someone who has been there (and is there currently) on a chevy 1.5 ton restoration.
Try past the 18K mark already... Of course, I paid way too much up front for a truck taht was supposed to be what it is now! remeber, its easier to buy than sell too!!!
Good luck in your decision..
