I need to replace three OEM Toyota/Lexus lug nuts (M12x1.5) and was thinking I might as well get a set of locking ones. Use one per wheel (duh) and have a spare OEM one. The Gorilla Guard 63631 with the spinning outer shaft seems like as secure an option as any, but the sizes aren't a perfect match. I only saw it mentioned once here in the forum and the person said it fits their model, so maybe it doesn't have to be exact.
The 63661 is a 0.685" (17.4mm) wide and 3/4" long shaft, whereas the OEM ones are ~20mm wide and 0.5" long. Will that smaller diameter pose any problems for holding the wheel in place on that stud, or should the seat of the nut be the only thing clamping it down? I would need to take one of the nuts off to see if there's enough depth for an extra 1/4" of shaft length.
