Was a while ago when i did this but as far as i can remember i went like this.
1.Car up on stands
2.Remove plastic Engine + Trans covers
3.Drop headers (10 x 14mm nuts + 2 x 12mm bolts on flex joint + 2 x 12mm bolts on hangers)
4.Remove Heatshield (4 x 12mm bolts)
5.Support tranny with jack so you can remove both crossmembers (4 x 17mm bolts + 4 x 14mm nuts) This will allow you to shift the tranny to the side so the linkage bolt has enough room to slide out (fouls on the body otherwise)
6.Push reverse lockout yoke up and stick a bolt in there to hold it up so you can remove the pin and cable.
7.Unbolt the front stay,this should give you access to the linkage.Remove the bolt and replace the four bushes.
8.Do everything in reverse making sure the reverse lockout cable is clear of the tailshaft.
9.Enjoy smooth and precise shifts again.
I found it to be the easiest way as i couldn't get the rollpin for the linkage out.Should take you around 2 hours with the right tools.
Hope this helps
