6.5 in Car Speaker Slotted Adapter Ring
A 9 mm spacer ring that adapts an aftermarket 6.5 in speaker to a factory door or dash opening, so you don't have to buy a brand-specific adapter or hack the sheet metal. It is 178 mm across with a 140 mm through-bore. It has eight radial slots, all covering a 148–164 mm bolt circle. Four 3.4 mm slots take #8 self-tapping screws for the speaker. The other four are 4.8 mm slots for #8 screws into the door, counterbored 8.6 mm wide and 3.5 mm deep so the screw heads sit flush under the speaker flange.
7/8/9 mm Push-Pin Trim Rivet Sprue
A snap-off sprue with three two-piece push-pin trim rivets, the barrel-and-pin kind used on Honda, Toyota and VW door cards, splash shields and dash panels. Each barrel has a split shank: 6.7, 7.7 and 8.7 mm OD with a 0.55 mm barb, sized for 7, 8 and 9 mm panel holes. Its heads are 18, 20 and 22 mm across, the grip length is about 10 mm, and a matching 4.2, 5.2 or 6.2 mm pin pushes in to spread and lock the legs. Measure your panel hole with calipers and use the rivet one size up from the hole.
