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 !
