Body Mounts and Bushings for 800s

[rweller@domain.elided]

I have a '71 800B that permanently leans like its turning left.  I think that I
have a shot body mount bushing or a collapsed body mount.  Super Scout does not
stock these for the old 800s (darned you lucky Scout II owners), but I wonder if
the S-II body mounts/bushings will fit (or can be easily modified to fit) on the
800s.  

Anyone have experience replacing body mounts or bushings on 800-series Scouts?
