You should be advised that on many early 13-cab F15As you may well not find any chassis serial number anywhere on the vehicle other than that on the door-mounted data plate - which means that if the data plate's gone, you're on your own. You might have limited success crossreferencing the engine number with another vehicle which has a known chassis number, but only if the engine is original; other than that it's basically "pick one", preferably close to that of another another known, registered vehicle of the same era; I don't know the legal technicalities of that, but I imagine the government motor vehicle lackies can advise you, and that number they accept would have to be stamped into the frame for verification.
