I thought all 14 bolt rears were fully floating? I could be wrong. :)

There aren't any e-Lockers for a 14-bolt unfortunately.  There is not enough room in the differential for the electro-magnet.  If you want a selectable locker for the 14-bolt you are going to have to go ARB.

Not all 14 bolts are FF some are semi floaters. If your 14 is a FF and open differentials then your next choice is a Detroit locker.

i believe that are full floaters. i have to remove the axle shaft to get the drums open. so i think that's what they are if not how would i tell.

that is the easiest way to tell.  semi-floating the drums pull off the with out removing the axle shafts.

Post a pick of the diff.... as far as lock out hubs go, maybe not so fast....... depending on what transfer case you have things might be a little more complicated. what does the top of your 4wd knob say? you may have a np203 transfer case, which is a full time transfer case. Search part time conversion for np203 case .

e-Lockers are available for the D44 front-end, but they cost nearly as much as an ARB.  You are looking at around $800 retail for just the locker!  A Detroit will cost you about $600, so it is only a couple hundred more for a selectable locker if you are going for it.

its a daily driver, I would go with a LSD in the front.  having a locker in the rear would be plenty.

ya its a np203.  after reading the thread about converting the 203 i don't really see a point. with a air locker in the rear i should be good. unless I'm missing something.
