H150F gearbox input shaft splines

[Guest]

I appreciate that most of our ELCO 80 owners have auto boxes but some
don't. So before I ask on the 80scool list I have a question for all
my pals here.
Does the 24 valve engine have the H150F gearbox, and if it does, does
it have a different number of splines engaging the clutch disc than
with the box as fitted to a 12 valve? TIA all.
