Reading your article on rear end changes prompted me to add some more food for thought. I just took out a set of 3.07 gears I had in a 65 Chevy 1/2 ton. It was in there for twenty years and had replaced a set of original 3.73 gears. When I ran H78x15 tires it was great around town and on the freeway. During the years I added a tire/rim size which is near a 10x15. It was still good on the freeway but was a dog around town and when hauling loads. I assume you have a four speed in your truck which has a little better gear selection than my stock three speed. Now the new 3.73 gears have a better overall performance for what I need, but I'm still looking for another gear for the freeway because the 3.07 ran so high. I would talk to as many people about this because you don't want to be changing these out too many times!
