My car has this mount for the passenger side (uppper engine mount): CV6Z-6038-C BRACKET - ENGINE FRONT SUPPORT
So my guess was that either the first version may have been rev b or rev a, and the 13 part would have a different prefix, maybe DV6Z-6038-A or something, but without a vin from that build range I can't check.
I might not be able to check for this information soon, so there goes nothing.
Hopefully that's slightly helpful.
