Richard, thanks for responding.
I tried glow sticks, metal fish, 10/3 wire to fish new antenna wire. Walked away after no success. Later this afternoon I tried the DEPSTECH flexible camera connected to my iphone. Worked like a charm, first try. Pull the AM FM antenna wire, Sirius XM wire, and left pull rope in event I need to do this again. Radio now has better reception with XM coming in loud and clear.
