All about how to make grid reference systems. Before you try to make your own you should read this page:

One thing that has always frustrated me in ArcGIS is selecting coordinate systems. ArcGIS does feature a “favourites” options for coordinate systems but this only appears in a couple of dialog boxes.
The solution: Just copy and paste the coordinate system files to the same folder as all your coordinate systems.
On my computer the path was C:\Program FIles (x86)\ArcGIS\Desktop10.0\Coordinate Systems.
Now when I browse they appear right under coordinate systems.
