PART NUMBER: 61-2843
Your stock NA Miata's carpet flap / jack cover is probably all distorted like an old potato chip.
This one is made out of ABS plastic to last a lifetime!
Laser cut to the exact same size as stock, including the 6 'mystery holes' (these holes may have been for attaching to the carpet by rivets).
Textured surface on the top to aid in glue adhesion (glue not included).
This plastic can be stapled into if that's your preferred installation method.
