Looks like the driver's side fender is fiberglass?? or patched??.
As well, there I see some differences from my '77. The side mirrors are mounted on the front of the truck and not the doors, which seems wrong for this year. Also the side marker lights on the fenders are not correct. In the engine bay the air cleaner is definitlly different from mine, not sure if that means the engine is a different year or been relpaced or if it's just a different air cleaner.
The box sides look great. Not original tailgate and no pics of the inside of the bed so not sure what condition that is in.
If it is not full of bondo it looks pretty good for $4,500. There doesn't seem to be too much rust.
Is it a good price canadian marty?
