This may be a "no duh" for some but for those who haven't yet had the opportunity to replace the clutch master cylinder. Removing the lower dash (knee panel) interior trim panel to gain access to the retaining nuts will make the job a lot easier. Using a long extension and a universal joint you will have pretty much (there is a wire harness to contend with) a straight shot at both retaining nuts.
Hope this helps
