I looked at my old VC tcase and don't see any thing other that some numbers stamped on a cover and some more on the center case. If the tcase is off vehicle: hold the input shaft and one out put shaft. The other shaft will trun with much resistance. The resistance is the VC. Make sure the center diff is unlocked If on vehicle: raise the front end off ground, and turn the front shaft. If there is great resistance it is a VC. I don't remember it the tranny need to be in N or not???

If it was a 93 or 94 it could go either way.
The rear extension housing is longer on an HF2AV (viscous) vs an HF2A. I don't have specific numbers but the difference is notable. Look at the rear housing on yours and then look at the one that is out of the vehicle. One of our employees has a 92 but is off today. I could measure his vs mine later, if you like.
That's okay about the locks. My signature card unlocks all of the dorms whenever I need in. I work for BYU Vending Services and that is just one of the many perks. When I checked this morning my card still worked...
Sorry to drift off-topic : but here are the rough measurments.
The non viscus transfer measures about 5 and 1/2 inches from the front mounting surface of the rear extension housing to the back of the rear output flange. The viscus transfer measures about 9 and 1/2 inches between the same two points.
