The top bolt between the tranny ant the xfer case is UNDER the shift housing.
You have to drop 'em both, remove the shift housing, then separate them.
When you put them back together DO NOT RE-INSTALL THE TOP BOLT.
This will allow you to drop just the xfer case in the future.
That's my story, and I'm sticking with it.
Dropping the tranny is the hardest part of this mod.
