About to do the clutch nut secure job, should I change my clutch while I'm at it

[xsephirot]

So I've decided I need the peace of mind to do the red loctite and extra torque down the clutch nut. I'm at 18.5k miles. Should I just go ahead and change my clutch pack while I'm at it? I haven't noticed any slipping. How long does a wet clutch usually last?

How long depends a lot on the operator.  69k on my OEM wet clutch.  When apart, measure stack height, then decide.

How many mm should it be at minimum? Thanks for the help
