OHO! You lucky SOB, someone has installed an auxillary transmission where your carrier bearing would normaly be. Then ran the shifter for that up in the area where the axle shifter would have been. Somewhere on that casing the gear ratios should be stamped.
The extra steel and springs your seeing are factory, perfectly normal for this truck.
