This place makes them. That said I do Not see them on their current website. See pics below.

NOTE Part Number on my slip, its small. The car pictured is NOT mine, and probably a early second gen Camaro.
NO holes drilled in the "Boot" lid. I bet they would make them for anyone using this part number.
This can keep KEYS, and for my part it keeps my wifes fingers ( rings) off the paint
