I had my 99' Rs up on a lift, and was about to install some Kartboy shift link bushings. A friend of mine noticed that the bushings where the shifter fits into the linkage were gone. It made perftect sense, because I have alot of play in the shifter when in gear. neither of us could figure out what to call these bushings, and I was hoping someone here could help.

 

They are called shift joint control bushings.
you will need to have two of them, and use some white grease on both bushings & the retainer bolt. The bolt must be installed from the bottom side with the nut on the top side of the shifter rod.
