I ordered a black G2 diff cover for my wk last week from amazon. Stock length MLL's are on their way also. In my last vehicle, 2002 dodge dakota I once punctured my rear diff cover on a rock so it has always been on my list to replace the one on my wk.

It went on fine. The only hitch was you really need a 6mm allen key on a socket drive to get it tight. I used a t40 bit that was close. You will need an 8mm key for the drain/fill plugs.
Remove old thin cover:
Inspect gear oil. Mine was changed at 52,000 and at 71,000 still looked clearish new. Awesome
Scrape old rtv with a razorblade. Get it clean and dry.
Add new provided black rtv all around the flange and around each hole.
Install new cover with countersunk cap head screws. 44ftlb
Let the rtv dry for a few minutes then add 2 qts of 75w/140 full synthetic gear oil.
Note: i removed the cheeseball sticker from the center. Looks better bare.
