1973 Dodge Sportsmen Fireball (front hubs and wheels)

Hello everyone im new here, my wife and I have recently purchased a 1973 Dodge Sportsman Fireball. We've been working on the brakes and I'm not able to separate the Hub from the rotor so I decided to buy rotor and hub assembly from rock auto but they do not fit. does anyone know where to purchase this part or know what the model is for the motorhome to help me purchase the correct parts. I know now its not the b300, so maybe the r or M 300 im really just not sure?? Any help would be great. Also I was just going to ask if anyone knows where to purchase new Wheels for this model, when do they need to be coined like the original. Im thinking they do but i really have no idea?

Back in the day Dodge chassis for class C motorhomes were a real mess when it came to suspension , brakes and wheels .

Does your Dodge have single rear wheels ?

Coned lug nuts on the front wheels and different rims ( duals ) and lug nuts on the rear ?

My second new vehicle was a 1973 Dodge B200 maxi van and I started working at a Chrysler dealership in 1975. Two local RV manufacturers were building on Dodge chassis at the time and many new owners were dismayed by the requirement of two spare wheels & tires on approx 15% of the cut away chassis.
I believe that the front spindle , along with the rotor and brake caliper, are different between the chassis that uses the same rim front and rear. The differences revolve around the FAWR ( Front Axle Weight Rating ) and I'd thought the parts on the lower FAWR cut away chassis were the same as the B300 ( one ton passenger van ) .
Unfortunately the Chrysler parts department employee who would confirm this , has passed away , so personally I have no one to contact to confirm my thoughts on the parts.
I'll dig around to see if I can confirm any of my thoughts , but for parts ordering you should provide any FAWR and GVWR info you have for your chassis .
I'm not aware of any replacement rims available for this vintage of chassis , just remember that during rear wheel install , alignment between the two rims was critical , and I can't remember if all chassis and rims used an alignment pin to avoid damage of the rims .
Could you post pictures of the original rotor and the part you received?
