TX WTB Radio cups Please

[NicoSlam]

So I purchased an AM/FM original radio for my truck. I purchased a new 4x10 8ohm speaker and a bracket set but I believe I am missing something because I cant figure how to attach the radio to the dash face. The brackets I have hold the speaker to the dash, speaker to radio and firewall. I believe I'm looking for "cups,washers and nuts" but not sure. Can someone be kind enough to provide a pic and/or have these items for sale. I'm dieng to get this radio in the truck to enjoy the small fortune I invested.
