Ah, I always remove them together, so I never ran into that issue.

Once I helped someone else try to line up the clutch once with the
transmission in the car, and it was such a PITA I resolved to never try it
that way again. Even if the input shaft just happens to slip right in first
try, it's a big pain getting to all the bellhousing bolts. And it's not like
leaving the tranny in place actually saved you any trouble in the first
place -- you still wind up loosening all the mounting bolts and supporting
it with a jack just to try to get it lined up.
