Hello all, I’m a new member. I have an old farm truck I just acquired from a 43 year old ownership; It is titled as a 45’, but she (the previous owner) said it was a 46’. It has current CA title and reg but is registered to the engine number. The VIN data plate in the engine bay is missing. The engine is original as well all the running gear (axles etc) I Have used the information on this website to look up some of the identification letters and numbers but I still have not definitively determined what year it is: It had engine BD747xxx and rear axle stamp on housing is BK 1690. The truck also has the following features which may help: 6 boards in the bed, split (with seam) original headliner, passenger door with lock on door not handle, and the later style inner front fender braces. So Based on the information on the site some of these features would indicate that it is later as in 42 to 46 but they only talk about differences between the 41 model and the later 42 to 46 models I’m trying to find a difference between 42 and 46 model. The numbers on engine and rear axle seem to indicate its a 42’ but what about the date? 1690? Help!!
