Generation IV External Engine - LS3 throttle body seal???

The only T/B seal that I can find for a LS3 intake is the GM #12576549. And, it's over $17 + $15 shipping. It's listed as a LS2 throttle attachment seal. Is there a aftermarket seal that fits the LS3 intake?
Thanks,
Rob

the FAST 90mm does not. it is too thin. I couldn't find any, so I bit the bullet and ordered the LS2/3 seal.

Ordered one from the dealer. $24.09. $17.20 from GM parts direct, but I don't need anyother parts, and it would be another $15 for shipping.
On well!

if you ordered it from us, guaranteed flat rate shipping of 6.75

i know its not much of a diff, but it is less$$$

^^ Is this the O-ring seal that goes on the intake??? Or is it different??

this is the o ring type seal that goes on the front of the intake for the TB.

Thanks...I've been piecing my setup together one part at a time and there for a second I thought maybe there was another cork/rubber type seal that attached to the back of the TB...

cork is for SBCs lol. and very few LS valve covers.
