Greetings, I am in desperate need of an ABS Module for a 2003 Kitty Hawk Lincoln Aviator with traction control and Individual Vehicle Dynamics (IVD). The 2003 model can only use one of 2 part numbers for the ABS Module. I have been to numerous Pick-Your-Part locations and spent $1000's in wrong parts and return shipping. The part numbers are: 3C5Z 2B373 CB or 4C5Z 2B374 CA The ECU won't recognize any other part numbers. Any assistance finding one of these two part numbers will be greatly appreciated.
