I have a 95 TA.

I had a TB painted and was going to install in in my TA, the problem is upon comparision the linkages are different. The one I want to install is from a 92-94 vette but it had the fuel rail with the diagional cut into the intake so I am thinking a 94. It was a none vented opti car for sure.

my 95 TB has an extra linkage connector. I can take some pics. But someone might know off hand. thanks a bunch

 

the bottom MPFI coolant plate of the TB is the same, just the linkage is different. the 95 has an extra linkage.

 

I believe the main difference is the 92-93 LT1 TBs had a provision for the throttle kickdown cable for the automatic trannies.
