Hi folks I'm looking for these two pieces that go on either side of the Interior behind the rear seats that latch the cargo floor.

I'm posting photos of what I have in my car but the part that I need is the same triangular piece with a notch in it that catches the optional cargo floor board that came in the 2012 Countryman S.

 

I believe you are looking for This.. part #11 I believe.
I would suggest printing out that diagram and bringing to a dealer to confirm, but that diagram should help your Google's!

 

WOAH, that was fast, Thank you so much Geekd4d!!

 

Looking at www.realoem.com it looks like the part numbers are 51479807003 and 004 Retainer for support, cargo floor item 10. Look at both pictures.

 

What grussel said.. #10 not #11

 

Ordered the parts left and right from the dealer and installed. All is right in my Mini world now.....Next week, The SS Downpipe, SS Brake Lines go in.

Thanks again folks,
Ozzie

 

It's the little things that make the world if a difference

 

So you need 9, 10, 11 and 12 to complete the catch? 8 is the old cover piece?

Any pics of the install or is is obvious where everything attaches behind the panel?

 

So I just did this. You need 9 through 12 and 13. For 13 you could use bolts or a rivet. It is a LOT of work to install item 10. You need to take half the car apart to get access on the left side (on mine) as the stereo amp is in the way. The left side I could manage through the vent hole and a lot of scraping.
