After completing the body off restoration on my 67, I have developed an annoying rattling sound under the car on the drivers side. The sound is tinny but I do not see anything under the car that could possible rattle.
The sound starts at 2500 rpm and remains at all rpms higher while driving. At idle or in netural I can bring the rpm up to over 3500 rpm without any rattle.
I noticed the side exhaust cover and molding rattle a bit when I bang on them but they shouldn't make noise at exactly 2500 rpm each and every time under load.
Do the side exhaust mufflers have baffles in them? I am wondering if a baffle is loose or rusted out since the mufflers are 18 years old and perhaps banging inside the muffler.
Any ideas will be helpful.
