Hmmm... The part I got has two plastic sections (one is the front silver section, that holds the R-Design logo decal) and the back (that's a black plastic housing that clips onto the grill with some plastic tabs and two metal clips I couldn't figure out). I was able to separate the front and rear plastic sections on the replacement by pushing out the plastic tabs on the front section that go through the back section and hold them together. The assembly is held together only by those two tabs and centered by a central tube and plug (which doesn't secure anything place but helps locate and align the two parts). Then, using only my fingers, reaching through the grill from the front, I was able to do the same on the old one, separating the parts by popping off the front section (the back stays attached to the grill) and then I just pushed in the new front silver section. Unfortunately, the front silver section's part number, 31290666, doesn't appear to be sold separately by Volvo.
