Right now my K5 has a 12 bolt 3.42 rear. Would I feel much of a difference if I swapped in the 10 bolt 3.73 rear? I have 33 12.50 15 tires, 700R4, 350TBI. Or would it be better to just swap out the gears to the 12 bolt? I don't go crazy off-road. No mudden or climing over large objects. Also, what gear would be better? Thanks for any suggestions.
