street lynx pinion angle ?

[wireweld]

For those using the street lynx on a 70 - 72 dart, what pinion angle are you set at?
With the tranny down 1.4 degrees, I have the pinion set at 1.6 degrees yoke up, I still feel a slight vibration at 65 mph and up. I wondering if I should go up some more on the pinion angle or not.
