I made a makeshift replacement back when they changed that. You can install Tampermonkey on Google Chrome and use this:

// ==UserScript==
// @name         /r/2007scape post flairs improvements
// @namespace    http://reddit.com/u/Fr0stwing
// @version      0.1
// @description  Post flairs for /r/2007scape
// @author       Fr0stwing
// @match        https://www.reddit.com/r/2007scape/*
// @grant        none
// ==/UserScript==

(function() {
    'use strict';

    //Adding the crown to J-Mod post flairs
    $("span:contains('J-Mod reply')").html("J-Mod reply " + "<img class='jmodcrown' src='http://i.imgur.com/diJgEKK.png'>").css("background-color", "#FFFFCC");
    //Adding Gnome Child to Humor post flairs
    $("span:contains('Humor')").css("height", "15px").html("Humor " + "<img class='gnomechildpng' src='http://i.imgur.com/QnprHR2.png'>").css("background-color", "#e6ffe6");
    //Adding the logo to the Achievement flairs
    $("span:contains('Achievement')").css("height", "15px").html("Achievement " + "<img class='achievementpng' src='http://i.imgur.com/ROg7gwX.png'>");
    //Adding a flier to the Discussion flairs
    $("span:contains('Discussion')").css("height", "15px").html("Discussion " + "<img class='discussionpng' src='http://i.imgur.com/fGk1oSs.png'>");

    //Adding CSS in JavaScript
    var style = document.createElement('style');
    style.type = 'text/css';
    style.innerHTML = '.jmodcrown{position:relative; top:1px;} .gnomechildpng{height:12px; position:relative; top:2px;} .achievementpng{height:12px; position:relative; top:1px;} .discussionpng{height:12px; position:relative; top:2px;}';
    document.getElementsByTagName('head')[0].appendChild(style);
})();
