Outer Limits 4x4 Board

Hi all
I need help choosing the right lock right for a gq front diff. I believe this is the right one part number 3210 (see link)

and the other i found is part number 3220, it says rear but i didn't think you could get an auto locker for the rear. (see link)

Does anyone have one of these in the rear of their patrol? If so is it any good on road or does it make it a pig to drive?

Thanks Brent

im pritty sure they dont because the rear is lsd in the gq and as far as i know they dont make one for that set up i tried shiming the rear lsd so it was locked all the time but it only lasted 2 weeks and broke all the plates in the lsd pack so i put a air locker
ps the locked rear is a real pain in the a#$ on the road in a lifted car

I have a Lockright locker that is still in the box, suits front diff GQ. Make me an offer if your interested.
