How do you remove the two pins that attach the fender liner to the fender in the rear of the wheel well? THey looked like the ones that you push the center in to release them. I tried that but they wouldn't budge, and when I tried to pry them out they tore.
Also, does anyone know where I can get a replacement?
The one closest to the front of the car that holds the fender liner in place is 20664092, then there are 2 more push pins that hold the fender liner in place and those are 11589290 I believe.
I've look everywhere for something that looks like what came from the factory, but cannot find it. Attached are pictures of what came off my car and what GM 11589290 looks like. The factory clip appears to have a long center rod that is pulled out then draws 3 arms from the inside. I got 11589290 to work, but it was a pain because you first have to draw the fender liner in close. So nothing special about 11589290 so you could pretty much use any similar style 1/4" push clip.

On the factory clip there's no head on it. Imagine that rod much longer and sticking out of the hole and the three arms lying flat. Then you insert through the fender and fender liner holes and pull on the center rod it will draw the end of it and start extending the three arms until the fender liner is snug up against the fender. Then the center rod breaks off at the top. There's no reusing that one.
So what they put on in the assembly plant and what they sell to replace it are two different pieces. Now I'm obsessed with that factory one. It's a pretty ingenious little clip!
The plastic pins are much bigger in diameter than the screws. He's saying that the replacement plastic pin is different than what is used during assembly and that the ones used during assembly are not sold to the public and he is correct. The workaround to this finding someone that works at a GM plant, showing them the part schematic, and having them tell someone on the assembly floor to cross reference their internal part number with the external part number of the push pin. Then have them grab you a handful of them.
I was at my local hardware store a while back and found one of these freaking poly fasteners. They are called plastic rivets and you need a plastic rivet gun to install them. Like metal rivets, they draw the surfaces close together and HOLD THEM from the inside, unlike push type fasteners that just squeeze outward. Also like metal rivets though, they can only be used once. This tool and rivets are available all over the internet.
They go through the fender and into the liner right where the edge of the inner fender lip meets the liner (rear side of the wheel opening, closer to the door), one at the bottom and one near the belt line of the fender. The service replacements from GM are push-pin type rather than plastic rivets.
If you already have the reusable push-pins in these locations (which it sounds like you might based on your posts above) then someone must've changed them at some point. All four of my 4th gens, '98-'02, came with the rivet style from the factory.
all the cars I have worked on have not had rivets in them.....strange
That is a bit strange, but not entirely inexplicable. On my '02 car, someone had improperly jacked up the car and broken off a chunk of the fender liner at the bottom on each side. To replace the liner I had to remove the factory rivets, and I replaced them with the current GM parts counter reusable type at that time. So that's one reason why you might see some examples that have been changed since original assembly.
