I own a B250 (1994), but I'm seeing many 5-lug B250s. Does anyone know the differnce between front axles on the 5-lug vans vs. the 8-lug vans? (regardless of trim level)

I am looking for compatibility here, specifically if it is possible to use 8-lug rotors/bearings on knuckles originally meant for the 5-lug rotors/bearings.

The Dodge OE knuckle part number covers both the B150 and B250 knuckle (OE 52058415), but does not specify how many lugs the van came equipped with. Interestingly, the B350 knuckle has four different OE part #s.

One consideration would be rotor diameter, the 5-lugs are listed as 11.75" whereas the 8-lugs are listed as 12.82", but I'll figure out the caliper mounting after determining which rotors fit on which knuckles, as I may be using aftermarket calipers anyway.
