    Took a little longer to get here than expected. My new radio head was shorter than the factory radio and the hole was on the far (driver's) side so the factory antenna cable came up 3" short! The extension fixed the problem and works like a champ.

  • Just what I needed

    This is a nice adapter to allow you to use an aftermarket antenna on a newer GM radio. I have a classic 1969 chevy pickup truck that I put a GM 8 track tape player into for nostalgia purposes. This allowed me to hook up the antenna easily. The right angle connection made installation easy.
