At the swap meet last Fall, I bought an antenna pulled from a newer Mustang (looked 94-96) for $5. I installed it right away on my '89 LX, as it screwed right in. However, I didn't get great FM reception, and never any AM. Well, I had thought it was my ancient radio, but the other day, I got an AVIC-D3. Same thing (decent at best FM, no AM). Can anyone confirm or deny that they are different? Perhaps the piece that screws in on a Fox is longer, creating a better ground? I don't know. Before anyone asks, I have no ignition problems. Same exact reception whether the engine is started or not.
