No reference on how big they are.
Maybe next time put a ruler next to one in the photo.
If I had to guess they kinda look like they might be spring expanders. Back in the muscle car days they would put those in the coil springs to lift the car a bit. Stick it between the coils and "screw" it in with a rachet.
Cheap and easy way - till they worked their way out.
It's been 49 years since my HS pal put them in his car though so just a guess.
