74 d200 Question

Looked at 74 D200 with a factory 440 this week. If you tried to take off quick,(punch it) from a dead stop the truck shuddered pretty bad. Also it made some noise in reverse when I turned around to go back. It has a 727 and a dana 60. A friend of mine thinks it might have a 2 piece drive shaft and it could be the carrier bearing and or u joints. Another buddy thinks torque converter. What do you guys think. It only has 58000 miles and is in pretty good shape. Thanks in advance.
