Weird.
They work for me at this end.
I'll cut and paste the info here:

From my notes on another computer I'll just stick with the LT5 S6-40:
thru '90 the part # on the tag should be 1052 000 031, '91 1052 000 035,
'92 1052 000 045 now the confusion, early '93 1052 000 045. These are all 610 Nm assemblies.
later '93 1052 000 047, '94 1052 000 081 These I believe are "black tag" 540 Nm and still have "lift ring"!
The only LT5 crash through "blue tag" '95 1052 000 087. No lift ring.
I guess I'll be embarrassed as hell if this isn't correct but I do believe it should be. I would guess there will be some crawling under the car this weekend!

One other point that interests me. I never thought you could just swap a connector to use the later speed sensor in the '90 cars. I thought the '90 cars were maybe 2000 pulse DC (sq wave) and the '91 and later 4000 pulse AC (sine-wave). I don't know this to be fact but it's the way I always thought it. I went to a good bit of effort to buy an original spare from Vauxhall for a Carlton that shared the ZF transmission with the Corvette. It arrived in an original Delco package. It was a very good find and the parts guy from Vauxhall was astonished that I found him. He had NO ZF stuff and the Carlton people I've corresponded with say the parts are likely harder to find in GB than they are here.
--------------------------------------------------------------------------------
I based my thoughts regarding the VSS on the fact that a '90 car shares the CCM/BCM with an '89 car and I thought those early TPI cars were 2000 pulse. The CCM/BCM changed in '91 along with the VSS's and those I believe are 4000.
The VSS I received from Vauxhall was the only available and I believe the fellow worked hard trying to find me another one or two. I didn't need it but purchased as spare.
Something just came to mind and I mean "just", usually the speedometer looks for the signal from the ECM with most early GM cars. Maybe the speedometer might see a 4000 pulse but I expect the CCM/BCM still wants to see something else for the odometer. I sure don't know but I'll stick with my thoughts for now!
