Had mine out twice now,
the HD NPC unit eventually tossed it in during a dyno run a while back.
just had a look in my old build thred in the platinum lounge, I may not have added pics of the selector removal when I done the first clutch.
There are some pics of the transfer lever somewhere though. Maybe that thread on the SS boxes getting stuck in one position?
I find its easiest to just remove the shifters individually and shove some rag in the holes.
as fraz mentioned, just take a bit of care around the gaskets and that silly looking plastic cup thing on the transfer lever. Be absolutely certain everything seats back in on assembly before tightening any bolts around the selectors!
if you chose to remove both drive shafts, have a vessel ready to catch a bit of oil.
