Placing the mounting studs in the second hole allows for a 20-degree change to the Super Duty transfer case, while placing them in the first hole allows for a reindex of a bit more than 10 degrees. The metric Allen mounting bolts that mount the ring to the transfer case are countersunk to ensure that the spacer fits completely flush to the transmission and transfer-case mating surfaces.
