Next is the removal of 1 13mm nut at the rear of the shift carrier.
Use a exacto knife or a razor blade to cut the end of.
Once you cut the sleeve off you can push the rubber to the other side to remove it.
Now your shift carrier should be like this (or similar).
Now you may press the Garagistic front carrier bushing in.
If you also bought the rear Delrin bushing. The following are the instructions for that.
Installation requires that the edge on the back of the carrier be grinded down a bit.
You can see the metal file we used in this picture and the Garagistic rear Delrin bushing (can be bought here).
Next step is to burn out the old bushing on the rear carrier bracket.
Hammer in the new Delrin bushing with the chamfered end in first.
It may be a good idea to "dimple" the metal housings after putting the bushing in.This will ensure that the bushing doesn't slip out the back. Use a punch and hammer for this process.
