Pretty simple you can knock it out in an afternoon. However I deleted all that rear heat crap that supposed to be in the way years ago. You'll need :
10&12 mm socket
What ever tools for hose clamps
10 in extension to make life easy
U joint or 10 mm wobble for the
Ds rear cover bolt
I did use a 12 mm wrench to break the tb top bolts loose better angle for me. Note: put the bottom TB bolts through before putting it back on. I used a flashlight to see to put the 12mm/10 ext on em. Remove the air filter can then you can sit there while you work.
Cleaning supplies. Paint if desired. That'll add a day plus any other while I'm here crap. Oh and a seal puller for the tube seals. If you've done the axles you should own one.
And if your seals are brittle, you will need a nice pick and tiny pry bar.
