Just take a 1.5” long piece of 3/4” bar stock, drill and tap 1/4-20 in one end, drill a 1/16th” hole in the other end for a piece of tuned 16 gauge music wire, then drill and tap an intersecting hole for a set screw. Insert the music wire, make sure the whips are tuned. Add thread lock and to the set screw and spray paint. Totally custom and fairly simple.
