pretty much what the title says, im about half way through a rebuild on my 93 lt1 throttle (it needed a hefty cleaning after 182000 miles) and i cant seem to find a gasket set for it. everyone i find is for 85-92 throttles, they look similar but i want to make sure i order the right stuff. anyone know where to get a set? thanks in advance

Shoebox has the answer for the manifold gasket, about 2/3 the way down the page, on the left side:

http://shbox.com/1/Parts.htm

1993-1997 Throttle body to intake manifold gasket - 10105379

But the part number for the top and bottom plate gaskets is only for the 94-97 throttle bodys.

Though not specifically listed in the parts book, I think the top/bottom gasket kit would work on a 93.

Is it possible the 93 bottom plate is a bit different, to accomodate the screw-in type IAC valve? Not sure.... just a thought?

just talked to the guys at tpi parts and they said the kit for the 85-92 tpi throttle would work. the only difference is the top plate on 93 lt1s got a rubber gasket where as the tpi throttles had a paper gasket. im fine with a paper gasket so i went ahead and ordered one next purchase is an aluminum throttle plate to replace that garbage plastic one. thanks for the help guys! i think im finally done with this throttle rebuild, on to the alternator

Comparing the two exploded views on my site, the bottom gasket sealing area looks pretty much the same. That was what I was basing my opinion on.

i can get you a picture of the bottom of the 93 throttle body if someone has a pic of the 94+ we can compare them and know for sure if its interchangeable. let me know if interested.

I don't know that a picture is necessary. The exploded views are already on my website (unless they differ from the actual, but I doubt it).
