Throw in some Lunchbox's front and rear , and Keep you Spider gears in your tool box .
I've run 3 different Lunchbox lockers in different Jeeps
Lockrights ( JUNK pins sheared after a year or so )
Aussie, Pins are larger then the lockright uses 4 less springs but they are thicker Pretty decent I had no issues with it.
Spartan, My Favorite of the 3 it was the easiest to install (comes with wire to hold the pins and springs in for install made it a huge help, The pins are massive and springs sit under the pins I will be purchasing one for the front of my XJ and 2 for my YJ

I see another problem with what you plan the 4.10 gears and the 35" tires. Have you used the tire/gear calculator on this site to see what you need?
I'm just getting everything together now well have most all now. I'm running 33x12:50x15's on my 99 and after running the numbers here I found that I needed a min of 4.56 and really 4.88. Mine is not a DD but you will find speed/RPM/Gear all shown for what ever you plug in. Also you can run 2 sets side by side to compare very nice to have here for us to use.
I can't remember who pointed me there but sure did me a favor. BTW I'm using Detroit Lockers front and rear now, that's a long story.

No back to the lockers. I dont drive this thing much ts a weekend wheeler. I have owned it for 2 years and put 4000 miles on it. A selectable locker in the rear is out of my budget. Everybody had pretty much agreed that a LS is a waste of money.
So I guess my way to go is lunchbox lockers front and rear....
Driving with a lunch box isn't bad at all. When I was 19 I installed a lock right in my 2002 F150 with the 5 speed. I put 20000 miles on that truck over the 8 following months before I sold it. It would get a little herky-jerky turning but never was a problem if you accelerated through a corner or coasted through with the clutch disengaged.
My XJ has an Aussie in the rear. I've yet to notice anything, the auto does a great job with it. I'd drive the it every day.
Both ratchet occasionally. I never really could hear it in the pickup and I just don't notice it in the Cherokee.

I'm locked front and rear. Front is a lockright, rear is a spartan. I also daily my truck not too far but about 30 miles a day, I hear some clicking in the rear and occasionally it locks and chirps a tire but doesn't bother me at all. I wouldn't even consider a lsd opposed to locker for what I do. And selectables were not in my budget. Just grab some lunchboxs and toss em in.
