I don't know which ones are and which ones arent. The quick way to tell if it is a full floater is to look at the hub. If it has 8 bolts all crammed together in a circle around the center then it is a full floater. Remove these bolts. What you are looking at then is the end of the axleshaft, it is the round thing you just took the bolts out of. Those bolts hold it in place to the hub. Now, pull it out and count the splines. You might have to tap on it with a hammer with a wood block to get it loose.
Have fun.
BTW - Seal it up with silicone when you put it back in. Otherwise the gear oil will seep out.
