I'm a twig so ill separate the removal for ease.
Bolts are out, it was much easier than expected.
Here's my 2cents worth-
Attach the socket only first to the bolt from the top of the engine. This makes it easier to attach the socket to the head.
Then crawl under the car from the passenger side so you are looking up at the drivers side d/shaft.
I'll start with the bolt closest to the centre of the transfer case-
Grab a 200mm extension bar and attach to the socket. Make sure the extension goes UNDER the old feed line (metal tubing with a flex section)
Attach the ratchet to the extension
Use a pry bar and rest on the housing so you rest the extension on the pry bar for leverage. This is the most difficult one because you are pushing with the pry with one hand and pulling with the other for the ratchet. I didn't use a breaker bar just a piece of pipe slide over the ratche handle.

See pics for a visual for the above. For the photos I removed the pipe (impossible to do without a third hand!)
