Bear in mind that because the panels are aluminium, filling in any holes is more difficult because you need someone who can alloy weld. Steel panels can be welded with a relatively cheap MIG welder at home.
The one you have found has the corner windows in the cab plated over (probably lots of pop rivet holes) and is the rack in the back bolted down to the tray or are there holes through to bolt it to the chassis ?
The price seems high, it looks more like $300-$400 to save it from being scrapped.
