I have always wondered if the first couple trucks they built for testing purposes and getting the contract are numbered like all the rest....dont know...so since they started testing in roughly 1966, it is possible, but VERY unlikely, that a truck built in 1965 or 1966 is out there...and there wouldnt even be a handful of those...very unlikely this is one of those but I suppose it is a possibility...
That being said/speculated on...the rest of the info above is fully correct...find the number on the frame at the front or rear and lets see what ya got!
Lord send your Holy Ghost into our hearts and make the desire of our hearts Your Will.
