The diameter and thickness of the felt wick changed in later years.

Does anyone have GM documentation stating the composition/material of the 216/235/261 felt wick?
They seem to be referring to the entire assembly as a "wick" in one of your attachments. The bakelite part itself is referred to as "plug 2.363" in the parts diagram which you posted.
Felt would last about 7 revolutions in that application.
