3400 plenum to LIM gaskets

[patgizz]

i need the 2 gaskets that seal the plenum to the lower intake. felpro only sells the whole set. does anyone know any places, or have a gm part # for them? i already did the lowers as preventative maintenance, but pulled the plenum to do the injectors and need new gaskets.

CarQuest has them as well, at least for the old 3.1 MPFI.

Fel-pro makes them. I used to have to PN around somewhere. I just need to find it again. I think I found it on carparts.com once before.

yeah i have the fel-pro number but the ghey local stores(autozone, advance) don't carry them, just the $50 complete manifold kit.

nobody carries a downpipe for a 3x00 w-body either.

If they carry Fel-Pro, they should be able to order it and get it in a day or two. Be cheaper than the whole kit and probably the GM gasket as well. IIRC, I think I paid like $5 for them awhile back.
