NOTES:
.
The symbol (L) indicates a locking rear axle.

Blank axle codes are for pre-production prototypes with 04G scheduled production dates.  It was common for such cars to be built with whatever was on hand and the records and tags made before rear axle gears were even obtained from a supplier.  While it was possible to special order GT-Es with, say, a 4.11:1 traction lock, which would have resulted in a “blank axle code” on the door tag, no GT-Es in regular production were ever so ordered.  It is believed, however, that several buyers ordered other gear ratios and had them installed at the delivery dealership.  This probably accounts for several GT-Es with Detroit Lockers installed and the decals for same in the glove boxes.
