I did some work which required I remove the headliner, and I broke the clips in the rear corners.
I can't find the things ANYWHERE.
here one is, broken in half. I can't find the other half.



Here's where they're supposed to go - strangely, not listed as an item in the diagram -



It's not #2 in that image, that's a metal clip that grabs the plastic part I'm looking for.

Any help finding this would be greatly appreciated. The headliner rattles without them.

 

try this part: Part #: PEL-911-HL-04 at pelican parts

 

OP - Can you shoot me the last 7 digits of your vin and a valid email address via PM? I might be able to find the exact one for your MINI.

 

So, I totally missed these posts. I ended up buying two BMW clips part 51438183314 from a guy on eBay. They didn't have the "wings" like the one in my picture but they did work. No more noise from the headliner!
