Edit coordinate info in locator xml

Note: This may be a stupid quesion (if it is then it is due to my lack of understanding of grid systems)
Hi,
All my files are in NAD 83. So thought I would make changes to the coordinate system defined within the location style (i am using dual range and the default coord system defiled is WGS 84). But I am stuck with the values of the precision grid values for NAD 83 (don't know what they are). Below is the code segment from the xml file (red highlighted is the area of interest):

<coordRef><type Sync="TRUE">Geographic</type><geogcsn Sync="TRUE">GCS_WGS_1984</geogcsn>
<csUnits Sync="TRUE">Angular Unit: Degree (0.017453)</csUnits>
<peXml Sync="TRUE">&lt;GeographicCoordinateSystem xsi:type='typens:GeographicCoordinateSystem' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xs='http://www.w3.org/2001/XMLSchema'xmlns:typens='http://www.esri.com/schemas/ArcGIS/10.1'><WKT>GEOGCS[&quot;GCS_WGS_1984&quot;,DATUM[&quot;D_WGS_1984&quot;,SPHEROID[&quot;WGS_1984&quot;,6378137.0,298.257223563]],PRIMEM[&quot;Greenwich&quot;,0.0],UNIT[&quot;Degree&quot;,0.0174532925199433],AUTHORITY[&quot;EPSG&quot;,4326]]</WKT><XOrigin&gt;-400&lt;/XOrigin&gt;&lt;YOrigin&gt;-400&lt;/YOrigin&gt;&lt;XYScale&gt;1111948722.2222221&lt;/XYScale&gt;&lt;ZOrigin&gt;-100000&lt;/ZOrigin&gt;&lt;ZScale&gt;10000&lt;/ZScale&gt;&lt;MOrigin&gt;-100000&lt;/MOrigin&gt;&lt;MScale&gt;10000&lt;/MScale&gt;&lt;XYTolerance&gt;8.983152841195215e-009&lt;/XYTolerance&gt;&lt;ZTolerance&gt;0.001&lt;/ZTolerance&gt;&lt;MTolerance&gt;0.001&lt;/MTolerance&gt;&lt;HighPrecision&gt;true&lt;/HighPrecision&gt;&lt;LeftLongitude&gt;-180&lt;/LeftLongitude&gt;&lt;WKID&gt;4326&lt;/WKID&gt;&lt;LatestWKID&gt;4326&lt;/LatestWKID&gt;&lt;/GeographicCoordinateSystem&gt;
</peXml>
</coordRef>

Can any one let me know the values of the following for NAD 83:

XOrigin
YOrigin
XYScale

ZOrigin
ZScale

MOrigin
MScale

XYTolerance
ZTolerance
MTolerance

HighPrecision

LeftLongitude


Thanks!
