Gave the guy a call. Says he has too many projects (67 nova, and a 71 and 70) and this needs to go. said the good is that the gauges all work including the ones in the console, has a factory dash tach, comes with an extra rear bumper and that the motor has been rebuilt within the last few years. Doors line up and everything and he says the floorpans are solid. the bad is that the truck has a patch where the tire goes (hatchbacks never held out water good anyway), it was an ac car, but not anymore and he has the heater box off, but the box is a non ac box. the glove box door is there, but it needs a latch, and the rear bumper is rusted out on the inside and he said something about angle iron on it but I'm not sure what he meant by that. The paint is faded and might buff out a bit, but would do with a new paint job eventually. He's not sure if there is bondo, but the body looks straight with no rust showing he says.
If all checks out and it runs and goes through the gears fine, I think I'll offer $4500 and go from there. Apart from the paint, everything else doesn't seem too big a deal and wouldn't take much to make nice. They guy sounded pretty honest about everything. He doesn't know his schedule tomorrow, but hopefully I'll be able to take a look at it then.
Oh, and forgot to ask if it's a true ss or not, but I'm not too concerned about that anyway.
