hi
for the linkage the bushing are the same at both ends.
the easiest way to replace is to put the car in park, go underneath and disconnect the linkage from the transmisison.
then go in the car, pull up the carpet around the shifter, undo the 4 bolts and pull the whole mechanism with linkage out
replace bushings at both ends (putting the new bushings in some hot or warm water make them easier to install)
install in reverse order
