What are the details of what ratio (w/w/o LSD) is going where? IIRC 2018 - 2022 all use 3.13 ratio. Where is the 3.77 coming from, I only ask bc 2IS AWD 350's never had LSD but the case is the same and would in fact bolt in but you loose the LSD (if yours had a Torsen?), unless you gut them both and swap in the LSD to the other gear and case. Which, if you're going to that effort, you may as well install a better LSD like the OS-Giken.
These are the numbers you're looking for (3.77) but I made this for AA81E vs A760E trans in the 350 2IS. And ya, I was in a hurry and didn't include the 7th and 8th as it wasn't part of the discussion at the time.
