You need the Plastic Rivets can get a set at Harbor Freight...
lol i meant harbor freight, no clue why i said that. i didn't even drill them because i didn't know they were rivets, i yanked them out with the trim toolHobby lobby works, (didn't know they had those rivets there) ? They don't have any telescopes!
Just drill out the center and the legs on the back of the rivet will loosen, and you just pull it or pry it out with one of those small fork tools, needle nose, or even a small flathead screw driver.
They come right out.
