Exhaust vibration/noise?

[FunElan]

It seems like everytime the car is moving at 3000 rpm, I hear some sort of buzzing noise. I'm thinking it might be the centerpipe, because the muffler looks pretty new. Any ideas as to what it is?

My car just started exhibiting these symptoms. I was thinking of ordering new parts including the exhaust hanger donuts as well which are broken and missing on my car. For the exhaust hanger bushings at the trans, I see at 2002AD that they list an early style (2 req'd) and a new style (4 req'd). Would my car ('73) take the early style?

Thanks!
