There actually is. The 05-06 front portion has the rectangular hole shifted forward a bit from the others. The single mounting screw tab is also shifted back about an inch to line up over the bracket on the floor plate which is also shifted back.
I'm doing a swap right now and have the opposite problem. Due to the expense of the later shifter bezel, boot, and cover plate that snaps into the console, we swapped to the earlier front half but the rectangular hole is almost too far back for the shifter to work. He is going to need a leather shifter boot that does not sag down inside the hole or the shifter will hit the edge of the bezel.
This rig however, is almost a cobbled together mess.
