and if the driveshaft has never been out, the splines are so stiff/rusty
on some cars that you can't get the splines to move. I've had to drop
the diff to get a driveshaft out.

Dude you slide the shaft back to get the flex disk out, so it's for
quite a bit of lateral movement
except that really does not happen. this is not a f150 where the Diff
flops up, down and sideways and the splines have to slide. The trans
is fixed. the center bearing point is fixed, and the diff is fixed.
Yes each will move a little due to flexing and vibration, but in
practice the driveshaft length only varies by a mm or so. I have seen
some with splines rusted together.

There is.
- this would also keep the shaft aligned so the knuckles could drive
the car. All that is from my faulty memory from replacing way too many
flex disks in the distant past . . .
If the driveshaft doesn't telescope and shorten its length, the geometry
would indeed allow the engine to drive the car. If it does shorten,
however, things will get very bad very quickly.
