So I have to now figure out what I have in the rear-end... I was out for a weekend drive on the surface streets and was following another car down a road with a 55 mph speed limit. I was keeping up really well and I looked down and the speedo said we were doing 70! Something's not right here. I don't ever remember Dad's being able to get up to that speed (and I woulda tried). Radar has had me pegged at the right speeds (we have some of those "you are going too fast" signs that show your speed in and around the neighborhood) at 45 mph so I have no reason to believe the speedo is that far off. Tranny numbers match as a '46 three speed. What could the prior owner have done to the diff or inside the tranny while still making it look stock on the outside? The truck came with a box of gears (assuming from the tranny) so perhaps he somehow upgraded while keeping the same look and #s matching case? Engine is a '52 216 though.
