Hi Frank,
Yes, the one recess shows a cross indentation not unlike a Swiss cross. I'm guessing that.
what about tools...didn't the car come with a standard set of spanners, allens, space for a spare plug etc.? Last week I cruised TM and saw a post about a guy who built an aluminum box for tools and installed it under the hood (right side)against the firewall. I'm thinking of a "roll-up" kit with some essentials and using velcro straps to secure it under the hood. I'm afraid the styrofoam that holds the jack is too flimsy to hold a couple kilos of tools for the road. thx
