I bought a set of Ford OEM mudflaps but the hardware was not included. The bag was open and I assume lost. Can someone tell me what is needed? The Ford parts list shows part numbers for hardware included in the kit with no description and size. When searched it shows as obsolete. My mud flaps are without the lip kit number 16A550B. Any help is appreciated. Thanks in advance.

Update: The screws are Ford Part No. N811534-S61 - Hex Head SEMS M4.2-1.41 X 30mm (#8 x 1 3/16")
Speed Nuts are #8 and 1"L x 1/2"W - Couldn't find a part number
Push pins are OEM # W701855-S300 - Head Diameter: 22mm Stem Diameter: 7.5mm; Stem Length: 35mm
Hope this helps someone.
