I got this modification done last night. Very easily done. The shrink wrap and wire plus the buzzer ( in Canada, The Source calls it a -0060 or -0059 buzzer) total cost was $14. I used the 0060 part. It was a simple, fun project that was done with 1 cup of coffee! It will deliver lots of fun and an innner smile every time I deploy that sound. Thanks to Corfire and all the contributers to this mod!
