Many of these cars have that shudder on takeoff. The balls in the ball and trunnion front u-joint have worn a little hollow spot in the housing and set up a vibration when forced to rock out of their little ruts.

You can look for another housing, convert the shaft to a normal cross yoke and slip joint, or you can loosen up all your motor mount bolts and slide the engine and tranny to a slightly different position. You probably have 1/8" to play with to get the balls in a different resting spot.
