Nope they are both limited slip.

From what I know which some days is a lot and other
not very much, one has the split half way in the splines and the other is full splines. I rebuilt
mine last year as I had the half length splines and
put in the full length from a kit that cost about 180 dollars. If you would like I can send some pictures of what they look like.

Obviously the full length is stronger and less
likely to strip axle splines.
