Got it now---hope you're still tuned in:

If you already have the QD's apart replace all the parts----not "cheap" but better than them failing down the road.

E69Z-18 D434-A

&

E69Z-18 D434-B

Confirm with your parts guys or try NAPA etc etc and use those numbers for cross reference. I believe these clips and O-rings are kinda common to Ford in general so they should be readily available in the aftermarket---cheaper too.

Please let us know if the above isn't correct.
