lots of vehicles are in that situation, back then vehicles were titled by the calender year of sale, not by the model year, if it's a 52 model, then that's what it is regardless of what the title says - just need to insure that the ID number on the title matches the number on the truck .... you'll also run across vehicles that are titled as one year earlier then they appear to be because the model year production started late in the previous calender year, so just as some 52's were sold in 53, some 53's were sold in 52
