Based on the responses so far, I guess tha I AM the lucky owner of a sweet 91GL that I originally thought that I was!
  I guess the nostalgia of an old bus was making me lean in another direction.
  I think that I will take a member's suggestion and purchase the '74 for fun and see what happens. Hope my neighbors don't mind a retro flashback while in process. :-)
