Most any Truck shop can them. You can order on-line from places like this https://www.anythingtruck.com/category/htp-suspension-airsprings.html 
Do you have the part numbers?

Also, curious - why are you changing them? They usually last decades.

They are very weather checked and a couple are leaking
Tried the truck supply places here in town and no luck
I am going off the part number I FOUND ON one of the other posts

Thanks for explaining. Good luck with the replacements.
FYI - don't be too worried over hairline cracking (normal cracking) - here's some info on that.

Gary, Does your coach have 3/4" air lines to the front air bags? If so they are a real b**** to change the bags. The problem is getting the hose fittings off and the fittings out of the top of the bag as they are 3/4" JIC fittings and will not drop through the top mounting plate. I actually had to make up a couple of wrenches to get the fittings off.
The rears are a piece of cake, nothing special about these.
My bag numbers are:Front Firestone Air Spring W01-358-8897  Mich Spring Co
                               Rears Firestone Air Spring W01-358-9376 Mich Spring Co.

Plug those numbers and name into google and you will find your bags.
Another question is: How are you going to block your coach up to be able to change the bags?

Yes they are the 3/4” lines

Can you slip a sawzall (something like this: https://www.amazon.com/DEWALT-DCS387B-20-volt-Compact-Reciprocating/dp/B00ODN0S70/ref=asc_df_B00ODN0S70?tag=bingshoppinga-20&linkCode=df0&hvadid=80333120120409&hvnetw=o&hvqmt=e&hvbmt=be&hvdev=c&hvlocint=&hvlocphy=&hvtargid=pla-4583932699601769&psc=1 ) in there and cut the fitting off flush with the air bag? Brass cuts easily - if you have the room for the saw. Once the air bag is removed you can just install new fittings in the new bags.

Mike, On the right front bag I had to cut off the fitting and they are steel not brass, I used my M12 Milwaukee sawzall. They screwed them into the bag so tight that I could not get it to break loose. And of course you do not have any room to swing a 1 1/8" wrench, I even tried a socket and 1/2" drive ratchet and could not budge the fitting. On the right rear bag I cut a access window in the front of the basement compartment which made the process a bit easier. To remove the fitting I had to use a piece of pipe on the end of my long handled Snapon ratchet. These fittings were installed dry, no thread seal or anything.
After I got the bags out I ground out the fitting holes so the fitting would pass through.

I would strongly suggest that anybody that has a coach with the braid covered air lines perform a pressure test on all the hoses, and I would be willing to bet they will find a lot of leaking hoses. We tried braided hose on some of our trailers and went back to rubber because they started leaking after a couple of years.
