whats the deal with the new tranny mts.

I just checked ebay and the 2512 mounts they show look exactly like the one I need but they are the ones like pictured on the left when they come in. I had the part store manager pull up the 2512 on the screen and compare it to the one in his box and they are different. He couldn't tell me what the deal was either. I have no idea what is going on with the mounts.
