I have a 1976 chevy one ton 4x4 with d60. Front and rear 4:56 gears and a rear locker, new brakes front and rear, this truck runs strong is driven daily every part of the drive line is in tip top condition, under the hood is a built high compression 327. The truck itself is not pretty, but its perfect for a mud truck 3000 negotiable or trade for a 4 wheeler
