How do you remove plastic window rivet?

I was contemplating ordering from DMT, but unfortunately they wont ship USPS, so I wont be using them. My Uncle used to work at auto parts mfg plant and "acquired" some of these adhesive rubber pads that I used for the bottom of the glass. He gave a whack to Dad who gave some to me. 10 years later I found a use for them lol. Got LOTS if anybody wants some. Work great, very pliable once warmed up.
Detroit Muscle and others offer that rivet. Piece of rubber hose on a 1/4-20 X1 bolt with flat washer and nyloc nut works also.
