Wow! I went back through 7 years of old documentation and found a picture.
It shows the clips in question that run across the car for the middle bow and the dome light harness.
Vikki has a complete headliner assembly (rods, clips, etc) but understandably doesn't want to break it up. If anyone has a set of these clips or knows where to get them, please let me know!
funny thing... I didn´t have these middle bow clips on my car when disassembling it. And I didn´t need them for installing a new headliner... Worked fine nevertheless (fortunately! When thinking I could miss some of these clips...). No issues so far. Good luck finding these clips!
