"Click" on to "Our Store Front".
 
We are glad you have stopped by to visit.  We have begun making regular changes and additions to our site.  Be sure and check back with us often.
 
Our customers are proud owners of some of the finest vehicles on the road.  If you are reading this page, you are most likely one of them.  The vehicle that we are referring to are the mature coaches which were manufactured by GM. While many parts are unavailable for the older coaches, many can be produced on an "as needed" basis. Check out our "ABOUT US" page to get a complete description of our shop and the services that we have to offer.  
 
Our latest addition to our website is the upload of our BASIC PARTS CATALOG - SUMMER 2015 edition.  It is our largest addition by far.  It is located on our Parts Catalog page, as indicated on the toolbar to the left.  There you can download it onto your computer and print it for your convenience. 
 
Take a moment to sign our guestbook. Our current newsletter - AIR SUSPENSION - is now available online as our previously published newsletters.  Our newsletter is a free service containing technical information for keeping your coach fine tuned.   We cover a variety of issues and how to easily resolve them.    
 
Be sure to check out some of our other pages including our engine and remanfactured components pages.  There you will find some of the most common necessary products to keep your bus and all its systems in their best condition.  All of our remanufactured items are brought back to original manufacturer specifications including all new current upgrades. This is how we can give you the best possible product.
 
If you are needing to do some body repairs, check out our new body parts and channels page.  There is a selection of parts which we have available in limited quantities. 

If you have a Webasto or Aqua Hot heating product and  are interested in learning more about them or have a nagging problem that no one seems to have an answer for, you have found the right placed to go to.
 
We are one of the oldest Webasto stocking distributors and premier warranty and repair facilities in the USA. We are knowledgeable with the entire Webasto product line and offer free technical support world-wide.

Are you looking for hard to find parts for your GM bus? Look no further! We have a huge inventory in our warehouse ready to ship. From fittings to filters, hoses to gauges, we have a long list of those difficult to locate parts that many consider obsolete.  From older "transit" and fishbowl coaches, to "new look", from 4104 to 4905, we have a tremendous number of parts that you just won't find anywhere else.  If we don't have it in stock we make every effort to find it or supply an appropriate interchange. The listing of parts below is but a scratch of the surface of what we can supply.  Give us a call and let us help you.

Part #682692 Engine mount

As seen above, engine mounts are available in both rubber and polyurethane.  While the primary difference is composition, there is a significant difference in durability and price.  Admittedly, the polyurethane mount is more expensive, however, the amount of time between replacement is much longer than with the rubber mountd and is virtually indestructable.
