Yes, these V-8 parts are different from the six cylinders for sure. The bolt sizes around the pumpkin and the number of fasteners is the obvious clue. Inside the ring and pinion gears are different diameters also. The metal LSD tag is fastened to the casting bolts and is folded back so it is readable from the rear. No other obvious signs that it is a LSD.
