The changer is held on by two bolts per side.
The bracket just needs to go form the bolt holes to the bottom fo the changer.
It shouldn't be that hard to do.
Hell I could probably make one using a small sheet of aluminim, bending it to the right length, and drilling a few holes.
As fad said its not that hard to do it based ont he location if you just look at it.
I mounted my changer under the rear parcel shelf in the trunk versus the right hand trunk pocket, as it saves much space used for storage.
