Your suggestions for the TTB are spot on. And if I were to do anything that would be exactly what I do... I have been looking into a hybrid 44/50 axle... but not sure.... as I have been researching it, it looks kind of complicated for my mobile shop setup. The only reason I want to do it is to gain the factory lockers offered in the early 2000’s and get a matching 10.25 rear with lockers... grrr Jim, now you got me thinking again...
In reality, I am talking it over with Kallie, and we are probably going to be selling my Bronco. Her 4Runner does everything the Bronco can do, just more comfortably.
