Has anyone installed the 7 side wall panels that are available from Nissan parts? I ordered a set recently for my wifes NV2500 work van, but I refuse to pay $1.62 a pop for the 94 clips it takes to mount the panels. The clip part# is 01553-09611. These clips are available from various places in China for much less money. (100 clips for about $13.00 and free shipping). Anyone on here use the cheaper clips?
