After some careful examining and comparing posts and pictures, it actually has a Gov Loc. Not really having a lot of experience with the 14BFF, I have some mixed feelings on this as I have heard them referred to as "Gov Bombs" and it seems as though people avoid them like the plague. The 60 had a "Trac Lok" which Ive read wasn't the greatest either but seemed to do really well for what I do.
So what are your opinions on this? I did see one mod where a guy lightened the weight(s) inside of the Gov Loc in order to "lock" it earlier (I don't think it completely locks though?). He did this BC from what I read, the GL is supposed to lock at 15 mph difference between wheels which to him seemed like a pretty big shock load to the 3 pin spider? He thought that locking it earlier would lower that shock to the spiders.
Again, for what I do with my truck, I have a feeling that it will probably be fine but I do like to understand how things work before I use them so I welcome any info and or advice.

Any way it works out, Im still pretty excited to have what appears to be a fairly new axle that has been sitting for the last 5
