What's the going price to change a set of gears in the stock 10 bolt. Would love to go to a 3/4 or 1 ton set up, but I don't have the time or money for that now and these high gears are killing me with the 33s. Let alone the 35s I want to change to. P.S. Thanks to all the answers, this site is great. 1987 Blazer, 350, TH700R4, NP208, 3.42, Rancho 4", 33"
