Just got back and good news, vibration is all gone!

looks like the tires and the driveshaft were both the culprits in this. Tires were off balance from age and sitting, so new Cooper cobra 295's took their place. Took the car out and slowly went to 65, no vibes. Then 70,75 and still no vibes. Got up to about 95 and was feeling good and could feel a little movment and figured the drivshaft could use some work. I was tempted to go up higher, but I rolled on on a chp officer and she looked a bit suprised when I had blurped the flowmasters next to her.
lucky there was a exit right there, so I waved hi/bye to her and exited pretty quick there.
thanks for the help everyone.
