Quick Help: I need to put a 7-Speed cassette onto an 8/9

The only available rear wheel has an 8/9 freehub. The only cassette I
have available is a 7-speed. The 7-speed cassette slides around on the
freehub. (I knew this would happen but I tried it anyway.)

I need a quick fix. I know one can buy a spacer to solve the problem,
but I need to do something quickly until I can find one.

Any ideas?

If you have an extra spare cog hanging around, or if you have an old worn
cassette, you can put a spacer or cog (if you don't mind losing your biggest
cog) behind the cassette and try that out.

As someone suggested, use a small sprocket from a dead cassette as a
spacer behind the one you're installing. If you've got a Dremel,
grind the rivets off the 8s cassette that you just pulled from
service, and use the second sprocket from it to take up the slack. If
there's still some slop, try using a spacer from between the sprockets
on the 8s. If it's still sloppy, try putting both the sprocket and
the spacer in. (This latter tweak should be overkill.)

Technically, what you need is a 2.5mm spacer. They aren't hard to
get. Your lbs probably has one. Might it not be faster to call them,
find out, and if the answer is "yes", make a quick trip to pick up the
right part instead of futzing around with patches?

remove a spacer from your ( or any ) old cassette.
