I still haven't found that engine gasket kit pn yet...I've done some searching and have only come up with aftermarket sets, and GMPartsDirect listed a number for the 6.6 diesel when I typed in "03 Silverado 1500"...

I think thats the wrong seal for your style throtle body. I believe thats the LS1 style 78mm for a cable style throtle body. You need one from a gen 4 engine like the corvette LS2 with the 90 mm electronic throtle body.

I believe what you need is gonna be 12576549 Throttle body seal. I am being told special order, they dont have one in stock or a picture of it on the website. not sure on the sensor but I may have an extra seal laying around for it.

You were right! I showed up there and they gave me the 78mm gasket and I'm like...uhhhhh.
Then I told them look it up for a 2008 Z06 and they gave me one that looks like it'll work, so I bought that...$43.00 later...
