Hey guy:
go to this web site from courtesy nissan, the clips are the same in this area as the rear front cover. Just drag your mouse over the number and it will give you the the description and part number. I have found that there are two different diameters of clips and lengths. It's iether going to be p/n # 6313GB OR 63130GA. Hope this helps
