VESA 75mm to RAM "B" (1") ball mount for SmartiPiTouch case

I have a Smarti Pi Touch case for a Raspberry Pi and the official 7" touchscreen. The case has 75mm by 75mm mounting holes thar are VESA compliant. I want to mount the pi in my vehicle, and I already utilize RAM brand mounts, so this adapter should adapt the Smarti Pi Touch case to the RAM mounting system.
