Yes, as OldSub said, no need for stumpification. The numbers are supposed to be different. The ones you have there are identification numbers, plant, date, size etc. Check out 'Brads 41-47 trucks (just google it) and you will find the information you are looking for with regard to the id plate.
As for the title, just register it as it is on the title and don't worry about the vin number being on the truck unless they need it for some reason. Here in CA, you can have the Highway Patrol do a vehicle check and they place the number on the body of the vehicle physically...but again, I doubt you'll have to do that if you have the title...just register it into your name and have fun.
