I'm not sure when the official last date of production would have been before the line changeover for the '79s. This old girl has to have been close to the bitter end though; it's impossible to say that it was the last D150 with a 440, but it has a shot IMO. The underhood sticker is long gone and I haven't had a chance to look for a broadcast sheet or check out the engine/transmission for VINs, but I think it's still a cool piece. I can see by the door sticker wheel info that the rims aren't correct, but they do look cool. Truck is a Custom with factory A/C, buckets/buddy seat, Tuff wheel and AM/FM radio.
