Vette Servos?

[ls182]

Is there some kind of paper gasket too? I was told by a guy who has one that it needs an actual paper gasket for the servo itself.

This is the kit

The red rubber ring goes with the part to the right of it, the 2 black rings below go with the part to the right of them also, they are made of a hard plastic and not paper. You reuse the original ring off of the cover which would be the "blue" one. There is nothing else you need but time and patience to get the sucker in.
