Shimano freehub body compatibility

Which Shimano freehub body will not fit on my 1989/1990 XT hub ? Will
any new 7 speed fit ?

Sheldon says: "Virtually all Shimano freehub bodies are
interchangeable". In addition to the exceptions Sheldon provides, look
out for sprocket-to-spoke clearance. I've found that some cassette
bodies allow the big cog to contact the drive-side spokes. This is
particularly true when installing a cheaper cassette body on an XT hub.
I believe the XT hub was designed to have the cassette body recessed a
little more than other hubs on the Shimano line. The body itself will
fit on the hub, but the cassette won't. No amount of spacers will help
this- there's not enough room for a proper spacer.

Note: my XT cassette body *does not* look like this:

Mine includes an aluminum spacer ring at the inside end.
