Rear spoiler installation
 

hey everyone... i'm new here. i bought a rear spoiler for my base 370 z from e-bay (a girl had her replaced with a nismo kit) thinking i got a good deal since i got it for a lot cheaper... until i went to a local body shop to find out the grommets to attach it is missing, tried to contact the seller but that's history. anyways, just seeing if anybody can help me with this, like any other means of installing it - adhesive only, or somewhere to buy the kit. thanks..... :confused:

nuts and tape, looks like.
