Welcome to Airforums!
Your Argosy is sitting on a GM P30 chassis. When looking for parts the P30 is the key. On sites like Rockauto they will list parts as for P30 or Motorhome Chassis. The Motorhome Chassis is the P30 Chassis with some specific upgrades for motorhomes.
For brakes, if you have front disc and rear drum brakes then your brakes are JB8. I think (but could be wrong) if you have discs front and rear then you have JB9 brakes.
The key to finding the right parts is reading all the little details and see how they compare to what is on your chassis!
