Very nice sneaky work there !
I was wondering about the pilot brg ...seems that you attended to that
as well as possible without making the project much bigger.
'some lube' on input shaft splines is important, I use a tiny about of
'black slimey' grease there ( molysufide I think might be the real name ) .
there's about 15 or more spots I lube in that whole bell housing/clutch
area.
A bit of lube in the right places really helps !
