I had been using my head to hold up the louvers rather than fork out the $60.00 for a pair of new ones. So I took one off and went to Murray Auto Parts and asked Jim the mgr. if he could match them up. He sold me 2 Strong Arm # 4423 and said if they didn't work bring them back. They work fine and the cost is about $36.00 for two and they have a lifetime guarantee. I replaced both so they could possibly not match up in length with one OEM strut. Sorry but haven't checked the trunk or door struts as yet. Ralph VIN 1606
