Someone else suggested that this combination might be the cause but I was not immediately convinced because the KVA's were designed by legendary GT40 engineer Kevin Atwell - I assumed he would have been aware of such a harmonic vibration.
In you judgment, would a design such as my KVA's introduce vibration or would the combination CV/U-joint combination cancel out any harmonic vibration?

John- to eliminate the halfshafts in this example- note the road speeds from 2k>4k in 2nd gear. Now in 3rd gear thru the same road speeds is the vibration present to a lesser degree, if so then your halfshafts are probably the cause.
