The ST Whammy Bar is not backward compatible with the Arc, Surge or other previous models due to a geometry change in both the baseplate and wire. We will continue offering standard Whammy Bar kits as well for a retrofit option.
This video shows standard (non-ST Whammy Bars) but the installation is the same for both products.
