What have you in the rear diff?
FWIW: I run D/L's front and rear.
Correct-Can't work if hubs unlocked.

open in the rear for now, i want a selectable for the rear. was thinking lunchbox would be good for front since it will only work with hubs locked...so in that sense it kinda is a selectable locker...kinda sorta

89 YJ 4.2L 258, AX-15 5spd, NP231, dana 30 front, dana 35 rear with posi, gears unknown
92 YJ 4.0, AX-15 5spd, np231, dana 30 front, dana 35 rear.
i have a lunch box in the front ive run that for years now with no issues the rear im going to get a posi. i know its not a true locker but since my jeep is on road as much if not more than off the posi is better suited for that plus the slight slippage i get between disk engagements off road isnt enough for me to notice. the strictly off road rig im building will have selectibles front and rear.

LSD is a very good choice for 'snow-country', on or off road.

so all and all, if I go with the brand Sparten from USA gear. i wouldn't be making a mistake?

I can agree that living in snow country an lsd to be a good choice, but would have to suggest a quality unit at least. I had a Powerloc once and it just didn't cut it, so I went with a switchable locker for big bucks. From what I have read New Mexico has some awsome wheeling areas.

With the Sparten-You depend(pray)the stock carrier can hold up.
With a Detroit Locker, you will never need to worry.

Ok Lumpy you almost got me convinced to go with the D/L. i dont like breaking stuff on the ol' jeep and ive had others tell me a lsd is more "gentle" on components. what about the set up or install should i say?

Gear pattern and backlash check will be the same for any new carrier.
If you have not done R&P work-Get a pro to do, it and watch what he does.
I say that as someone who has 50+ yrs experience setting up R&P's.
Would also be a good time to replace the front axle U-joints and axle seals.
Still-I'd do the rearend, before the front.
A D/L in the back end does takes a bit to get use to.

And if you go this rout stay off snow covered streets or you will find your back end wanting to pass the front end.

I'm a bit late to the party on this thread, so I apologize. But you might consider a Truetrac. Shares the benefits of an LSD with the true locking of a typical locker, but with out the noise or unpredictability of some other offerings.
