Source for seal on ignition coil - 2002 Sienna

I changed my spark plugs but lost one of the seals between the
ignition/spark plug coil and the valve cover. I thought I could buy
one easily, but I guess its not so simple. Toyota tells me its part of
the coil and to get it I'd have to buy the $90 coil. I suppose I could
just run a bead of silicone (and I presume the purpose of the seal is
to keep water and grime out of the tube, so silicone would probably
work fine), but if there's a source for these little rubber seals,
could somebody let me know. It looks like I can buy a spark plug tube
seal, but it seems that this seal is the seal that's under the valve
cover.

Thanks.

It looks like Murphy's law applies here. As soon as you apply a bead of
silicone, the seal that you lost will turn up stuck to one of the cross
members or splash shields. If you decide to go the silicone route, I would
recommend using one that does not harm O2 sensors, like the stuff used for
form-in-place gaskets.

If you know the diameter of the seal, how about looking for a similar one in
the plumbing supply section of a hardware store? The rubber may or may not
hold up as well as the one made for the coil.
