I inquired about adding a locker conversion to my 95 carry DD51T from a company called Phantom Grip. Here is their response. "This model seems so similar to the DB series. Do you happen to have access to the differential? We just need some info from the diff to see which part # exactly it is. Let me know if you do have access to the diff and I can send you a spec sheet of what we need." There you have it. I am wondering if anyone has access to a differential out of one of our trucks where we could get part numbers? Any help would allow us guys without lockers to easily add them without buttons or air lines. If not I will take mine apart but was hoping someone here would have that information? Lets do this guys!
