Jon,
    I had the pleasure of discussing this phenomenon at  length with Geoff 
Healey.
He says that the vibration frequency of the box frame and the interior body  
panels are not the same.  They come together for a harmonic frequency at  
about 55 MPH.
       Jensen spot welded the interior  body to the frame, thus it is not a 
solid structure with the frame.  
    The phenomenon gets worst in the later Healeys as  Jensen increased the 
spacing of the spot welds to save costs.
    The solution, that I have found is to weld 1/2" x  1/2" angle iron on the 
inside of the transmission opening extending the angle  iron down and welded 
onto the box frame.    
    This ties the inner body to the frame making it one  vibration entity. 
    I have attached a photo of the installation  outlining the angle iron in 
red.
