My son has an 05 F150 STX with suicide doors. The plastic cover that covers the striker on the headliner for the suicide door to hook on broke. It has 3 sets of numbers on the inside of it. Does anyone know which one might be the part number. I will try to post a picture.

 

Usually those stamped part numbers are Ford engineering numbers. The dealer can do a reverse lookup and find you the replacement part number and pricing.
