Your decals are a different style to the ones I recreated, I don't think you can find them for sale anywhere either.
Having said that, I have another vintage bike, a Dutch Benotto sub brand called Alimo. I had resprayed it in the 80s, that paintjob is looking a bit tired so I wanted to restore it's original white colour. There were some reproduction stickers available in Spain, but they looked wrong. Every few months or so, I'd do some internet searching, in a vintage bike group on Facebook, I found an original set of stickers that were exactly the same as was the bike when it was new, I couldn't believe it, I tried to buy them but they had just been sold, so I contacted the person who bought them and thankfully he sold them to me.
So keep a look out, sometimes old bike shops empty their drawers and you might find what you're looking for. Gary Fisher stickers aren't lacquered over so, the ones you can buy now can always be removed if you get lucky.
