Did you measure it right? Most frames and hubs are 120 (track) 126 (old bikes) 130 (modern road bikes) or 135 (mtb).

Just get a track hub and put a some small spacers in it. Be sure that when you tighten the lock nut, that the axle reaches the outside of the nut. If the frame is steel, you can probably just squeeze the frame together as you tighten the axle bolts. If you do that, be careful not to tweak the dropouts (they are horizontal, right?)

Surly makes some 130mm hubs that have track threading on one side and freewheel threading on the other.

I had the same issue when I converted my 80s road bike to a fixed with 120mm hubs. If you add 3mm spacers on each side you should be fine.

There were bikes from the very late '80's/early '90's that came with 128mm dropout spacing, so that either 126mm or 130mm hubs could easily be used.
