The wire is definitely something to fill a space -- probably due to wear in the slot or could be some wear in the linkage farther down that is allowing slop in the lever and they tried to get a better alignment to the indicator letters. That also appears to be the original version of the indicator clamp which was superseded by one having allen screws gripping the shaft for a tighter grip on the indicator wire.
I believe the wear on the other piece is due to the operator not lifting the lever enough when changing gears. There should be two stops requiring the operator to make a definite motion to lift the lever and clear the stops when going into reverse or park. They were designed to prevent accidental shifting into either gear -- particularly reverse -- if the lever was bumped or pushed too hard.
Here is a photo posted a few weeks ago by another owner of a 55 (whose name I can't remember) showing the revised indicator clamp.
