Will a differential out of a auto z51 fit a m7 z51? The differential on my m7 z51 is done, and I was able to find a cheap auto diff. I know gears are a lot different would that be the only difference?

It might fit, but the gear rations are wildly different, and vary depending on whether it came out of a 2014 (6 speed) or later (8 speed). I think the following numbers are accurate:

For all years, the M7 rear has a ratio of 3.42:1,

For 2014, the Z51 auto is 2.73:1, and the base auto is 2.56:1. For 8 speed autos, the Z51 is still 2.73 and the base is 2.41:1. All would significantly compromise acceleration.
