Hey Guys:   Looking for guidance.   As per advice read on this forum, I got under the car (1986 model) and twisted the driveshaft (ebrake on). There is about 1/8th to 3/16ths of play.   Problem isn't very noticeable right now. Little thump thump when decelerating at slow speeds. Some whine at highway speed. Only bother's me a tiny bit, but I don't want it to get worse.   Diff mounts look good.   I assume torque tubes and shafts are no longer available. Right?   What should I do now?

now, right now u should b here
