93 z28 LT1 throttle body gaskets - where can i find them?
 

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:

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 :yes: 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 :p

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).
