Default Hyperglide cassette on Hyperglide-C freehub body

The smallest sprocket has to have a built-in spacer, and there should
be splines in the spacer.

Sure it isn't an 8-speed cassette you're trying to put onto a 7-speed
body?

I see I chose poor wording when I said "The problem is that the
smallest cog has no splines to engage." It is indeed a 7-speed
Hyperglide, and the number and the spacing of the cogs is identical to
those on my 1993-vintage 7-speed Hyperglide-C cassette. The smallest
cog does have a built-in spacer with splines in it. What I meant was
that the Hyperglide-C freehub body, with its splines that don't go all
the way to the edge of the body, don't come up far enough to engage
the smallest cog's splines. This is what makes me think reducing the
spacers by 1 mm might work. I already tried removing one of the 2-mm
spacers, but it appears that that allows the lockring to screw in too
far. The result was that the freehub became difficult to turn, before
the cogs were tightly screwed down. I don't have a 1 mm to try, and I
anticipate having trouble getting one from any of the local bike
shops.

Thanks for your advice and for the time you've spent on your web
pages.
