When I just got the tool out, first I thought it was not going to fit at all.
Then I realized the flaring rod was fitting, to exact size, that is I had to push it inside, it was rubbing as it went in, but it did not expand the sleeve. Literally within 1 mil.
Then the anvil was not usable fir the socket further away from the bracket. Simply did not fit. I simply situated the eyelet rim on the anvil of my large vise, and then hammered onto the rod.
For the socket closest to the bracket, I could use the anvil.
This said, it did not mangle the eyelet rim much at all; maybe it is important for the projects where the part is used according to its direct purpose, and aesthetics does matter, but in this case it does not and is barely noticeable anyway.

As for the rubber, the sole purpose of it is insulating the socket electrically from the chassis, and so even 3-4 layers of black tape would do.
