Throttle cable and carb gasket/spacer questions

As far as I know, just the flange on the cable housing end in the engine compartment, and the "E" clip in the passenger compartment is all there is.

If there was a foam gasket or seal of some sort OEM, I have never seen one in a 40+ year old car. Once the carb end of the cable housing is anchored to the engine it should not move much.
