i completely disassembled my TB the other day so i could soak it overnight in Berryman's Chemdip. that stuff works awesome btw, my TB looks practically brand new inside/out now. before soaking it i removed the TPS, IAC, and also removed the aluminum IAC/vacuum port housing from the top of the TB (it's that thing the vacuum harness plugs into on top of the TB). does anyone have a part # for this gasket? it's rectangular shape paper gasket and is about 4" x 2" with holes to route vacuum (and boost :) ).

its not sold single. part # for TB gasket kit is 17112792 and includes that, tb coolant housing o-ring, the tb to intake gasket, and IAC valve o-ring. $10.xx on gm parts direct., $21 at the dealer. my parts/illustration manual doesnt list single part numbers for these peices.
