Found this clip whilst removing my damaged bumper but the other side was missing
I've asked Subaru UK and looked on many of the Subaru part sites (Megazip,jp car parts,Opposed forces etc) and it doesn't seem to exist so just wondering if anyone has any other checking out how to find what the part number is

The rectangular hole in the first picture is where it was remvoved from

 

Model, body and year might help......

Although you may find that it is part of the bumper cover and not a separate part

 

Apologies Don

It's 1998 Type R
New bumper was purchased from Subaru and nothing came with it
The gentlemen who replaced the bumper noticed that one of these clips was missing when he removed the old one and now the new bumper on the passenger side sits slightly under the quarter panel (drivers side is fine) and I think this clip should be able to push it out so it lines up properly.
I will get the bumper taken off and see if it can be adjusted without the need for the clip

 

Have looked through both JDM and Euro parts databases, but the part appears to be "missing".
It looks as if it clips to the top edge of the bumper cover and then locates in the square hole to keep the bumpers curved shape and as you say align with the body.

Maybe a candidate for 3D printing?

 

Yeah that's the odd thing it should be there but isn't
Thanks for looking Don and thanks for suggesting the 3D printing option 👍
