Like all optional equipment and accessories, whether factory installed or dealer installed and whether Ford authorized or not is that they add nothing to the judging score (in Early Ford V8 national meets) and only have the potential to cause a loss of points. Simply stated they either add zero or have a negative impact. So if you have one or a dozen, they better be true Ford items and exactly as they were when first installed during the model year of your car.

Yes, there are a lot of Columbia rear axles running around beneath '33-40 Fords and as result, the Club is a little bit pregnant viz-a-viz strict authenticity as it allows them without deduction. I understand that the AACA isn't forgiving in this regard (although like with all judging, the presumption is that the judges know their p's and q's).
