Hard to tell if it's longer without a W108 one next to it. https://www.ebay.com/itm/165629752177?chn=ps&norover=1&mkevt=1&mkrid=711-213727-13078-0&mkcid=2&itemid=165629752177&targetid=4580359295528871&device=c&mktype=&googleloc=&poi=&campaignid=437225724&mkgroupid=1228154759183859&rlsatarget=pla-4580359295528871&abcId=9300907&merchantid=51291&msclkid=16cb0f8cc8e81efe8cbb6bf8c688cd95
