Motor mount issues, still!!

Still confused, discussed this in parts wanted previously when I thought I didn't have the proper mounts. Couple guys posted pictures and diagrams for modifying the left or driver side 273/318 mount for a 360. I've now got the motor on the k frame. The driver side mount fits all three bolts but the passenger side would need to be added to for the third Bolt. What am I not seeing?
