Rare classic videogame repair parts, where to buy?

Archived from groups: rec.games.video.nintendo (More info?)

I'm looking for all kinds of rare repair stuff for retro Nintendo and
Sega systems. Parts like:

Screws used in controllers and systems
NES Styrofoams for boxes
SNES Cardboard inserts for boxes
Replacement buttons for official controllers
Fix-A-Pad and Fix-A-System kits (Doc's)
Cartridge bags (NES, SNES..)
+ everything i didn't think of

If you have these or know where I could get some, please reply or mail me.

Thanks.
