Looking to go with a 4.3 ring gear in the diff, anyone know where I can source these or what will interchange?

Tripoint engineering had 4.3 4.6 and 4.88 last I knew. You might also look into swapping a ford expedition 8.8 rear end in. They are all over the junk yards and then jegs will have any gear set your mind could think of. Plus its about the same price as the mazda gears
