My early 71 has a strange problem. Just under high idling, the driver side rear fender vibrates very noticeably where it curls towards the exhaust and around the side marker. There's also a pretty loud resonance under acceleration that I've been wondering about, and this could be it.
Is this a problem with early cars? I've not noticed it on the 74. Anybody experience this, and what have you done about it? Brace?
