Due to the age of your car, you might as well change both floor-shift bushings and linkage bushings. It's much easier to change the linkage bushings on a bench.

From under the car: disconnect the linkage at the floor-shifter. Remove the shift bracket at the transmission and slide out the linkage with bracket and front bushing. Remove the floor-shift assembly. Now you can replace both linkage bushings easily on a bench as well as the two floor-shift bushings.

With the brackets in a vise and a 19mm 12 point socket on one end, the linkage bushings can be pressed into the socket for removal and installation. No "special tool" is necessary.
