So I have an old jacket, really nice down, that I would love to keep using. The zipper teeth work just fine but the sliding piece is all fucked up, needs replacing. Anybody done this before? I found some on ebay you can buy but am sketched on do it yourself as far as this goes. I'm hoping there is some place in town that does this? I don't know. Could use any help, thanks. If somebody has skills I'm definetly willing to pay for thier services.
