Some of those things change between the G37/370/350. I'm pretty sure both 6MT and 7AT 370Z rear ends have the same input flange on the driveshaft side. And no matter what pumpkin I'm using, I need at least one axle-shaft if I'm switching from VLSD to aftermarket LSD (but not open to aftermarket LSD). But for some reason other than those issues, there's a difference between the 7AT and 6MT 370 rear ends (enough that LSD mfgs generally are 6MT-compatible only, or make a separate model for 7ATs). It's either that the much-higher ratio in the 7AT is actually a different diameter (in which case I don't care, that gear set is being tossed anyways), or it's that the inside of the pumpkin has an odd shape for some reason I can't fathom. In any case, though, it seems the common solution others have employed is to grab a used 6MT pumpkin and slap it into their 7AT car. I think the 350Z and G37 6MT pumpkins both work in that case. Anyways, I really don't know, something to research later in the week
