Rear of the motor should be the Firewall side, and it does appear that is the only one.
That part is listed as a rear for the 2008 GXP.
I would go to a dealer and ask if they have one, or see if they can order one then compare them in the parts department to see if your stock is supposed to be the longer or shorter.
If the GXPs are like the 3800s, you can get shorter dogbones (or as the GXP calls them "torque strut mounts"). Yours may be this kind for some reason, or a recall could have taken place.
