Larry,
The best price I could find on the front air bags were from Newell. If you haven't tried them you might want to try.

There are many variables and for some unknown reason Firestone puts the bag number on a paper label and attaches it to the mounting plate. To verify my air bags I had to remove them. Even then most of the labeling was destroyed & unreadable. Very careful comparison of the specs in the Firestone air bag replacement book led me to the proper air bags. Here is the Firestone air bag book:

If your coach is the same as mine here is the post with my numbers:

Removing an air bag is not difficult if you are able to remove and retorque a wheel. The hardest part is the corrosion and road grime on the hardware and air fitting.

Let me know if I can provide more help.......................

Larry,
I referred to the front, but it appears that you need them for the drive axle? Looks like yours are the same as mine. At least the W01-358-9447 is the same number as my drive axle air bags. Those should be available. Use the specs in the Firestone catalog for comparison. Pay close attention to the air inlet size and bolt pattern.

Hope this helps..........................
