I need to put back on my rear bumper cover. I lost it in an accident, so I don't have any of the fasteners. What holds it on, just some clips attached to the tabs that fit thru the aluminum bumper? Where can I get those clips?
I have 3 of the 4 clips that attach the sides of the bumper cover to the brackets on the fenders.

In addition, I will be replacing the bumper trim. Is that held on by clips that attach it to the bumper? Are those clips available?

My rear bumper was missing the large clips that hold the bumper cover at the edges. I just went to Ace and bought some 1/8" aluminum pop rivets. I put them evenly across the bottom of the bumper using existing mold marks in the plastic to guide me. I was replacing the center bumper molding trim piece at the same time and put some under there too to flatten out the bumper cover. I had a spot or two that was bulging up. With the trim on, you don't see the rivets and the ones on the bottom look original if you didn't know better and only if you are under the car. It's the little fix up projects that make an old car look nice.
The trick to installing the molding clip is to take the metal clip part out of the plastic part of the clip. Now install the metal part of the clip to the molding and install plastic part to the body of the car. Make sure they all line up to each other. Now slide the molding down over the plastic clips that are already on the car, catching those with the metal clips that are already on the molding. If you try to put the whole clip into the body of the car and then try and push the molding down into the metal clip, they will pull out of the body. You'll see what I mean when you try to do this little task. Even done the correct way, it is a little tricky to get the metal clips to slip into the plastic clips.

Two types of clips for the bumper cover. Thin clips that fit the tabs you describe, doubled up at each tab. Maybe 12-20 total. In addition, the upper edge of the cover and bumper are joined with 6-8 heavy clamping clips. Not sure if these are easily located other than at a dealer or salvage yard. For the bumper trim pieces, those are sold by IPD and alloem.

Not often you hear this, but clips are a cheap part down at your local Volvo Dealership.

The L shaped Chrome trim under the head light is over $100 down at your Local Volvo Dealer last time I checked on that one. The one on the right side of my trusty 245DL took two years to find. I have seen several since then, but that it the first rule when you finally find a part. Then you can find lots of them.
