Don't know if there are " pages"...
but there are lots of threads.....
main thing is to be sure you can loosen the top input plug before you take out the bottom plug...that applies to the differential also...
Sometimes the differential has never been opened up...and is hard.. if you search with my name as the poster you will find the pictures of how I used ' controlled mechanical advantage to get mine loose... hint... the hole on the side for lifting the rear right wheel is positioned perfectly....
The Redline MTL is the preferred fluid by the smartest guys on this forum... a search will reveal the reasons for that...

No filter, BTW.

do i need a 14mm hex socket to loosen the plugs, just like the Diff?

if so, i need to find one.

I do think it is the same size as most differential plugs..
Have you seen the bent wrench which comes with the car new ?
That is made for these jobs... Check Fastlane,Performanceproducts or Ebay...

Yes, it is a 14 mm and I remember having trouble because it is a tight squeeze in there. So the proper tool would be ideal.
