Most likely the linkage and the bushings and clips that make the connections.

There are 2 bushings and 2 clips.

Check any of the online parts places for your car > transmission > shift linkage and shift bushing.

The one on the shifter tang is done under the car and is awkward. You may be able to muscle it in. The other can be done on the bench after you remove the linkage.

Some heat the bushing in hot water to get it to go in easier.
