Tom, there was a quantum leap from the 46 to the later 47 AD truck. First and foremost (in my opinion) was getting rid of the %#$!! four piece hood which was just good for crashing down at inopportune times as well as chipping the paint. To this add door weather stripping, two windshield wipers, a stationary windshield that didn't keep the top of your pants leg wet, an out of the way parking brake, a sloped windshield and aerodynamic front sheet metal with the headlights incorporated into the fender, and after the first year the shift lever being on the column as a three speed option and you can see the truck really did have an advanced design. All that being said I wouldn't trade my 46 panel for any of them.
