pulled the driveshaft, and allllll the noises went away. swapped in the recently rebuilt driveshaft from my 80 and her truck was good to go. So nice to have a "spare parts" truck lying around.
Never had a driveshaft on an 80 just make a ton of noise with no vibrations or other symptoms, but now I know. Thanks to all for your advice.
