Thanks. I figured it out last night. Heres how I did it in the GoogleEditor.js client side script.
....
var calendarExtender = this._itemsManager._ce
this._itemsManager.CreateItem(this._itemTitle, this._itemStartDate, this._itemEndDate, " ", this._itemIsAllDay, null, calendarExtender);
Or you can access this way as well
................
if (hostPath == null || hostPath == 'undefined')
this._hlEditEvent.href = "http://localhost/<AppName>/CalendarEvents/GoogleEventRedirect.aspx?EventId=" + args.Uid;
else
this._hlEditEvent.href = hostPath + "CalendarEvents/GoogleEventRedirect.aspx?EventId=" + args.Uid;
var UserID = "&UserID=" + args.CalendarExtension[0].toString();
var EventTypeID = "&EventTypeID=" + args.CalendarExtension[1].toString();
this._hlEditEvent.href += UserID + EventTypeID;
