Matt has a '95 I believe.
As I mentioned in another message posted just now, I think '92-93
used a cable and '94-96 electronic. (And electronic for '97+
obviously.) I would guess that means all GenIs are probably cable
driven.
Do GenIIs with electronic speedos still use a gear in the
trans/tcase such that it can be corrected by swapping out a gear,
or is it only the cable driven versions that use the speedo gear?
