Choo choo motherfucker!
Known to fit hook style Subaru tie downs. I'm sure it will fit most batteries of similar size.
Modified from @tiddy on Grabcad's Subaru Battery Tie Down (https://grabcad.com/library/subaru-battery-tie-down-1) and remixed it for machining, with my own text. Included is STL, MX-8 (Mastercam 8) and SLDPRT (Solidworks)
