Well, if your cover has the same shape as this:
then it's a 14 bolt full float. The ring gear size is 10.5". If the cover is more of an oval shape, it's a semi float axle and the ring gear diameter is 9.5". Another way to tell is by looking at the hubs. If there are 8 bolts on the end of the hub, it's a 10.5" full floater.

Sounds sick man!! Wheres pics. It most likely has a FF.
If it is infact a 1 ton from the factory it will be a 14BFF unless it was swapped out for some reason. Just look for the large hubs sticking out of the center bore of the rim. Like pictured above.
