Hah, does that make my truck rare? From what I've heard, light duty 3/4 tons have 14 bolt semi-floaters, and heavier duty half tons have the 14 bolts. I've been told Z71s and light 3/4tons, not sure on the Z71's though. Mine has the 14 bolt, and so does a buddy's 6-lug 3/4 ton.
DirtyLarry, you've worked with GM for awhile right? What's the deal on that? Did the GVW rating constitute the 14 bolt option in half tons? Also, why were some 3/4 tons six lug?
Oh yeah, and if you do know those answers, maybe you could tell me what the deal is on the front diffs. I know 3/4 tons up have the 9.25" split case 14bolt IFS front differential, and half tons have the 8.25" split case 10bolt IFS front. But I've heard that the diesel half ton 4WD trucks did and have heard they did not have the 9.25". Which one's right; standard half ton diff, or bigger diff in diesels?
