In the arcane trivia department, many decades ago, California registered vehicles by engine block serial number. When an engine was replaced, the title was amended by DMV to reflect the new engine number. At some point, a bureaucrat recognized that the frame number was a more permanent identifier for most vehicles and the standard changed and eventually the frame serial number became the VIN and the engine serial number gradually disappeared from DMV records except for motorcycles. Not sure what PA does.
Getting back to the OP, is the VIN on your new paperwork anywhere on the truck? If not, what is the VIN on the truck? Is it possible that your aunt accidentally gave you the paperwork for a different vehicle?
As to year model on DMV paperwork, at one time California title contained a notation to the effect that year model designation is based on manufacturer data which meant that typically the selling new car dealer who submits the original paperwork for title and registration filled out the forms so clerical errors were possible. If the VIN protocol for your old truck contains a character for year model (like the 1st character in a Ford VIN) it should be possible to verify the stamped VIN and have that number corrected on the title without an act of Congress.
Correcting the spelling of your name should be a simple process.
Lastly, for a fee you should be able to secure photocopies of the old documents you surrendered to your DMV in order to get the current title to confirm what the "old" paperwork described.
Good Luck and let us know how this turns out.
