This is a pair of CB/ham radio microphone hangers designed to fit the revival 2nd-gen Toyota Tacoma
threaded accessory mounts made by
Coop68 on Tacomaworld. If you've got a pair of the new threaded mounts (not the originals by Lostsheep), then these mic hangers will fit your mounts.
There's two models available - this is the "mid" model, utilizing the bottom two threaded mount points, leaving the top threaded mount point available for a RAM ball or anything else that can utilize a 1/4"-20 hole. The other model, slightly lower, is here.
Each hanger requires a single 1/4"-20 socket cap screw, 1/2" long, to attach to the mount. I use
these from Fastenal. While the hangers could be installed on either side, the mic button cradle is intended to point outboard to leave as much access as possible to the climate controls.
The tolerances on the screw holes are very tight - thread the screw in to the mic hanger to start, then place the mic hanger on the threaded holes with the alignment pin in the bottom hole and tighten the screw until snug.
