'73 F100 vibration at 35

Drives pretty well, but has a vibration at 35mph.

Many ideas?

Vibration felt in the steering, or base chassis vibration? Meaning the whole truck is being rattled. At 35, if you drop into neutral, the vibration still present?

In neutral/ park,, if you raise the RPM slowly and steadily to about a matched RPM you would see at 35, any vibrations?
