It looks like the flywheel taper is seated completely, but I've never known of a properly assembled threaded structure having part of the nut sticking out. Do I need to pull this apart and see what is amiss, or is all as it should be? BTW, still haven't determined if the engine-to-bellhousing bolts are 1.25 or 1.00 pitch yet. I don't have a metric thread gauge. Another good excuse to by more tools!!
