The device pictured at the top is definitely not a VSS. I just looked at the one on my '90 Z, looks nothing like that. Looks the same as the one in my '93 I used to have. This is what the VSS looks like for the ZR-1's and the standard coupes with the ZF6, picture taken from kragen.com & does not show the gear that goes on the shaft (I don't know if the automatics are the same or not):

Apparently there are 2 different types of VSS, D9A & D9B (I also saw a D9E listed on Autozone.com, but it was listed as unavailable). I think the codes denote the number of teeth on the gear that goes on the sensor. One of those codes will be listed in the RPO code list under your console lid. My '90 Z has D9B. You can get a D9A from autozone, kragen has D9A's and D9B's. They aren't cheap though.
