Can anybody point me in the right direction? Can't find the part number and probably have to pull the bad one and hunt around for a new air shock. A part number or vendor who may have it, especially in Spokane area would be great.
Welcome to the forum Hochstrasser, a few of tips to get you started.
First is whenever working on yours or any other (AS) motorhome recognize you have two products, the coach and its systems, the chassis and it's systems. AS and the trailer owners are a great information resource for the coach, but when it comes to the chassis, it is just a Chevy/GM P30 chassis and treat it as such.
Second tip; the '78 Argosy is almost identical to the '79 Airstream MH. Although badged as an AS from the VIN numbers they were even made in the Argosy factory, so don't be afraid to search the Argosy and Classic MH knowledge bases.
In terms of your question, the air bags are covered in many many threads in those forum, but the site search engine isn't great at searching across databases; if you want to search within a thread it works great but if you don't know where to look, use a regular search engine but include the site name in the search criteria (for example on Google if you enter "site:airforums.com air bag" it searches the whole site, and you will get numerous hits all with different approaches to changing the bags - there is no one way, and many ways are model specific).
Lastly, you will get most out of the site if you put in a little 'leg work' (searching, reading other threads) because there will be posts from the last 15 years or so, and 15 years ago spare parts were more common (often parts referenced as available from an auto part store are now specialist) but they will have the part numbers etc.
To build on all of this, here is a video about installing the air bags (on a P30 chassis) showing the most commonly used approach - it is still a 'fight'.
