The fork on my 1977 Gitane Gypsy Sport seems to be improperly spaced. That is, the distance between the dropouts is correct, but they aren't the same distance from center.

The spacing used to be 94mm or something strange like that. Then some bonehead (me) just grabbed them and pulled to get the extra 6mm he needed.

Is there a good way to fix this myself? If I took it into my LBS do they have some absurdly expensive Park Tool gizmo that would do it in 30 seconds? Should I just buy the Sunlite chrome fork from Niagara?
