thanks -bob

Answer
Bob, yes, that is called  the tailshaft bushing and then the seal.  There is a tool that removes the bushing, then the seal just gets tapped in.  You do have to take the drive shaft down to remove the center bolt on the flange as well as pulling off the flange.  Hope this gave you an Idea whats entailed.  Must be a nice car.  Dont see too many of them like that anymore.
