Thanks BC! I will give the driveshaft another look but as I mentioned initially, I replaced
u-joints, center bearing, had driveshaft inspected & balanced at a driveshaft shop, while I stood there watching. It was smooth running up through 90 mph.

Ran truck through the gears with rear section of driveshaft removed & no vibration. Whle driving, step on clutch or put in neutral, vibration stops. Inside of transmission looks like new, no shavings, no visible wear on gears, bearing, synchros, or shift forks. Engine idles smoothly. Only other clue is a rattle in the shifter handle.

Any ideas or guesses??

Am yet to replace my differential but in the mean time, I want to use oil with a bit more viscosity.
