Thanks for the reply. As you can see from the attached pic, I have installed my cover. The passenger side stud is AG9Z-00812-D, the part itself seems overly complicated for what it seems to do. I would guess a standard hex bolt would serve the same function, perhaps with a nylon bushing on the threads and a washer under the head, but what do I know, use your own very good judgement. I am having somewhat of a problem identifying the correct stud part # for the drivers side, if anyone knows pls let me know. I bought the hood liner at the same time and am very happy with the resultant quieting of the injection noise, I guess if you are losing big bucks you do what you have to, but REALLY?
