thanks for addressing my problem with the vibration. I did some more digging in this club forum decided to take the drive shaft out and replace Ujoints but thay looked and felt new so I took it to a driveshaft shop.Turns out it was an out of balance drive shaft 10 grams on the front and 12 grams on the back of the drive shaft. dosent sound like much but what a difference I installed the driveshaft took the car out and got up to 98mph before I ran out of road and it is smooth as silk. yeha!!
