93 Supercharger Tubes

Does anyone know how to put those large diameter, as in 3 to 4 inch or so, supercharger tubes back together on a 93 sc tbird? I needed to pull them off to get to some other parts needing replacement and the previous owner had used silicone. Ford told me three o-rings are needed, but there are obviously four connections. Which connection doesn't get an o-ring or was ford's parts person wrong?

It's perfectly okay to just use a thin bead of gasket sealer. I've done both of my cars that way and they work just fine. I use the orange high temp kind.

You best bet when resealing the tubes is to use tbird88s IC gaskets. Go to the sccoa forums and contact tbird88 and tell him you want a set of IC gaskets. I believe they are $40 and are made of teflon.
