Automatic Diff vs NA diff

I have a quick question I may need to replace my rear diff pretty soon on my NA 1990 300zx. Is the diff on a automatic NA 1992 300zx the same or are there any differences? Because there's a automatic 300zx at the junkyard and if it works I may go pull it.

If both are NA they are the same does not matter if manual or auto. Look at the front diff flange to the drive shaft, NA will have 4 bolt pattern R200 diff.
(6 bolt pattern for twinturbo version R230)
