I just pulled a 3.73 LSD 8.8 today from a 95'
Three things on that list.. Well maybe even 4 that id personally change.
For the gears id go with a Motive Gear 4.88 RP save like $50 bucks.
For the brackets I would go with Artec Industries with truss, helps with tube spin and bending, but costs close to $400. Its what I have ordered!
G2 cover, id personally go with a Riddler if you can make it work, or a solid diff cover. Around the same price.
Then last, get the zj e brake cables that will work instead of spending $100+ itll be much cheaper, but a little more labor.
And like 4jeepn said, a full case locker would be ideal.
