the reason it's getting worse is because with the pedal pushed in, the driveline is now only spinning from the inertia of the rear wheels. with the clutch engaged(pedal UP), the entire driveline is now under pressure from the motor, reducing any vibration because there is active torque in the line.
think of spinning a basketball on your finger. as long as you keep it going with your other hand, it will continue to spin fast and smooth. once it begins to slow and you're no longer applying continued speed to it, it wobbles and dances around.

any suggestions to what it might be. and why it just now statred this the tranny and rear have been done for months
tailshaft bushing from not properly addressing the length of the driveshaft issue with installing a 3550 transmission. they make the spacer for a reason.
i was told by the guy that i got the tranny from said if i wasn't running to strong of a gear like 4.30's or more i would be ok w/o the spacer but it seems thats not true

The driveshaft balance must be better than perfect for a steep gear like 4.30's.
