I have a 2011 Ecoboost XLT Supercab, 4x4 (145 wheel base, 3.55 ratio limited slip axle). Can anyone tell me the difference, if any, between Ford OEM driveshaft part numbers DL3Z-4602-K and DL34-4602-GB?

Assuming their nomenclature follows any logic, the last digit or two could be a date code or generation designation.

Another source indicates that the number shown on the label: DL34-4602-GB refers to the "engineering code" and not a part number. The actual part number for this driveshaft is DL3Z-4602-K. Thank you for the above response and any other consideration.
