Rick has the answer. Fishing the center conductor through the opening in
the shield is easier if you provide a few inches of extra length and push the
shield up the coax so it increases diameter a bit.
The crimp terminals are ok but I personally would solder them to the coax
after crimping for long term reliability. If you use ring terminals, they
can be bent with long nose pliers to fit around the open wire conductors and
then soldered to the open wire conductors.

To answer the original question about lead dress on the coax:
"Something new" (to you) is to use tweezers to displace the braid
near the "base" (ie away from the end) such that a hole is formed
in the braid. This is done without cutting. Then, needlenose
pliers are used to grab the dielectric and yank it through the
hole. Sounds tricky, but I've done it dozens of times. For smaller
coax (up to RG58) they have a tool called a "lead extractor" that
makes this easier. See:

This tool is too small for RG8, but gives you the idea of what you
want to do by hand.
The other thing to do is install crimp terminals on the braid
and center conductor so that you are not soldering to the coax.
