Can anybody recommend a good shop in the Denver area to re-gear my diffs? Running 3:42 or 3:73 now, in the 10 -bolts. Might be picking up a 14 for the rear soon, but either way I'm looking to swap out the gears for 4:88s or 5:13s. Be running 35s on 'em. Looking for a reputable shop with reasonable prices, OR a K5 gearhead who wants to make a few bucks. Anybody?
