A couple companies make them like TunerRack but I think the biggest issue is that it’s no longer compatible with the scissor jack. A couple other issues are that the ones that use grub screws to pinch the welds can come off if the grub screws back out from vibration, and the kinds that require drilling sometimes develop obnoxious rattle if they wind up having play.

But the most unintended outcome of all this is usually those things are nice shiny anodized bits, so people tend to still use pads, which kind of defeats the purpose
