The rear axle would have been the stock rear axle. Does your SPID list the R05 option? Being a 3500 it would hae been an H072. Checking the axle code on the carrier will help confirm that.

Up front NAPCO built axles based on the H052 centersection.
Additionally they supplied the Dana t-case, lift block/stops, front spring mounts and hangers/brace, engine crossmember mod. parts ect. The PTO and the winch are of course options added to the basic "conversion" 4x4 parts.

As a package conversion the stock engine, trans and rear axle were used without modification. Even the park brake cables used the 4x2 guides and frame dimples.
