Default Acceptable Runout Driveshaft?

I'm trying to isolate a noise that appears to be coming from my torque tube. I used a stethoscope and found the noise seems to be louder near the driveshaft bearing area of the torque tube. I removed the rear end, then the torque tube, and examined the bearing and race. Nothing jumped out at me. However, when rotating the shaft I notice it seems to have significant runout, about .060 at the universal end of the driveshaft. Does anyone know what the specifications are for acceptable driveshaft runout on a Ford Model A?

Larry’s 40 posted about driveshaft round out, it was very informative! Sorry you need a new driveshaft .060 is way too much IMO
