Let's see...

I'd start with measuring the rear chainline (as per Sheldon Brown). I think the SS Surly hub chainline for their 135mm axles is 46.5mm while their 130 axle runs a 42.5mm line. My guess is that you're running a 135mm axle with a 46.5mm chainline (be sure to double check this tho).

If it's the 135/46.5 then it's probably just a matter of selecting the best spindle length to gain a usable chainline (again, as per SB).

The shorter axle might make things more difficult...

Once you know the rear chainline, you can start determining a ring size that will both clear your chainstay while meeting a "workable" rear chainline (by way of spacers, rear or front, as needed).
