First remove the trigger group from the rifle and remove the mainspring.
Then remove the current flat Safety Spring. Re-install the screw that holds the trigger spring in place. Sometimes it will protrude thru the bottom of the tang. You can take some meat off so it is flush or add small washer to take the place of the removed flat spring
Next tap out the cross pin that holds the safety bar. See pix #1 Below.
Set the new coil spring in place to see if there is enough width for it to fit.
See Pix 2 Below.
If so proceed to install. If not use a file to remove a little material (usually not more than .020" is needed) from the side of the safety finger where the spring will sit. See pix #3 Below where the pointer is pointing.
Install the new coil spring per the picture #4 and use a pin punch to keep it in line. See pix #4 Below.
Tap the cross pin back into place. Pix #5 Below
Check to see that it works and the leg of the spring engages enough of the safety. If not bend it in as necessary. Pix #6 Below.
