    Tried doing a search but no luck. My brother is putting a lift on his truck with 4 in. blocks in the rear. What size ubolts does he need (axle dia., length, thread dia.)? It's an 82 K10 and still has the stock 10 blt. I want to try to get some tomorrow before I go home or I'd wait and measure them myself.
