Silly question, but which way do the LSX motor mounts go?

Silly question, but which way do the LSX motor mounts go?

I'm talking about the stock clamshells that mount to the block itself. It seems as though they're not symmetrical, but rather one side has a double layer for the bolt holes, and the opposite side is not as thick. It looks like the horizontal hole in the rubber part of the mount is offset to one end of the mount too, so I'm assuming getting it on the right way is going to be important. Now, from my crappy cellphone pictures, can you tell if I have them on the right way, or do I need to flip them around upside down?

There should be a tab on the backside that keeps them from being installed upside down.

Mine don't have that tab. They're almost completely flat on the backside.
