Looking to pick up the 3.25 Final Drive transmissions. How do I tell these apart from the standard 4.058, 3.77 FD transmissions? Any identifying marks?

In particular, post #5 has the formula and method you have to use to identify the transmission.

It is also the same process used to identify SI from EX transmissions.

Another detail is which country you are in. A Canadian CX is a USDM DX. We didn't get your taller gearing CX being we didn't get the 8 valve D15B8.

In Canada the only real tall manual in the 92-95 was the VX.
