The 69 clips are designed to slip inside the finish panel and use the nylock nut you show in your pic of an original. Also, the stud on the aftermarket clip is too long. It will hit the lower trunk lip when the trunk lid is closed. The speed nut is also not correct and will only work if it fits inside the confines of the space allotted in the trunk lid l.If you look at the pic you posted you will see how much shorter the threaded stud is. When tightened down, it only comes to the very edge of the nylock nut.
Possible the pic from the supplier is a generic one though and you actually received the correct one. Do you have a pic of it?
This aftermarket clip might be able to be modified to work but not in its present configuration.
