When making a driveshaft, the manufacturer will want the static length,
with suspension on the ground, then will add some fudge factor to ensure
the splines will be safely seated at full suspension extension, yet
there is still a bit of clearance at rest.

Another caveat, Kelvin.
In some cars, especially if you have been playing around with ride height,
the distance between flanges with the suspension at normal ride height will
NOT be the shortest, i.e. fully compressed length.
I've seen a couple of V-8 cars come to grief over that, with the shaft
trying to be shorter than it can when the suspension bumped, which tried to
push
the diff and trans apart maybe a half inch.
What you really would like to know is the shortest distance between the two
flanges regardless of suspension position.
