Plastic back seat panel question

I agree these are the kind of things I keep running into. I took this car apart probably three years ago thinking that I would be putting back together within that same year. Just didn’t happen it kind of has come down to waiting on the painter. Which i’m sure a lot of us wait on. Thanks for posting the picture

Ok here is another question what kind of bolts where used to attach the panels to the support bar in the back of the car where the top pump is attached to? There is two for each side can someone post a picture
Thanks
