Fel Pro Part Number MS93334, it's a kit for that type of install. The manifold should have come with a gasket for the upper to lower. I made one for the adapter to upper, and had a new one for the TB to adapter. that FelPRo kit is available at autozone, advance, all those places. Get yourself some new vacuum line to replace the 10 year old stuff on there. I was also one plug short, found one at Lowe's in the plumbing section though, works like a champ. Good Luck man, later
