The Ford Barn

Just changed the u joint on my 1946 Super Deluxe. It has a 39 Ford transmission.
I have new bias ply tires that I personally balanced on a spin balancer.
The balance is absolutely perfect.
The wheels are true.
The tires are true.
Now that I have this issue corrected, I have a noticeable vibration that starts at 35mph and ends at 45mph. I ran the car all the way up to 65mph with no other vibration.
The car also vibrates on deceleration...whether the clutch is in or not.
The vibration comes on at 45pmph and leaves below 35mph.
Possible pilot bushing? Clutch? Pressure Plate? Bearing in the transmission? Torque tube bearing?

Any help/ideas would be great!
Thanks Guys.
