Don't think this will help, just an excuse to pass along an 
observation I made in my '80 Westi while crawling around underneath.

The mounting bolts for the propane unit have siblings on the 
passenger side.  If you need additional propane, there is a place to 
mount another one, with bolts in the right place.  Don't know about a 
non-Westi.
