foam rings sitting on switches

[foam rings sitting on switches]

I need the foam rings that go on the switches on the atari 4 switch model. And one atari screw. I saw the foam on ebay for 10 but as a 15 year old I don't have much money, so if anyone has it for cheap then tell me.

Oh, and where can I buy a screw for the atari, mine came used missing one

I opened my atari today.... and noticed that the foam piece on the switches are all dryed out and were practically falling off, when I picked one up it started to rip. Can anyone give any info of a alternative that I can use or a link of where I can purchase these pieces of foam that would be great! Theres one on ebay but its $10 and I can't spend $10 on a thin peice of foam, by the way I'm not cheap just a poor 15 year old
