Patrick,
The amount of play you mention is not unusual and probably not the
problem. I have found that most clunks on acceleration are due to
either U-Joints or play in the outward parts of the suspension.
Since you have checked the U-joints, the next thing to check is wear on
the bolt (or hole) that secures the vertical link to the trunion
assembly. Also check the bushings and bolts that secure the radius
arms. On my Spit, I discovered that the bolt that holds the vertical
link was worn about half into. I had to replace the entire vertical
link because the hole was also worn out.
Wouldn't you know it, that was the only part of the suspension I didn't
completely rebuild during my restoration.
