To make the BOB trailer fit, you could add spacers outside of the dropouts to build up the extra width needed to accept the BOB hitch.
The problem you might have is keeping the rear wheel clamped tight enough. I assume your frame has horizontal dropouts and the wheel can shift if it isn't very tight.
A better fix would be to cold-set the frame to 130 mm and replace the rear wheel with a current width (130 mm) hub and wheel. That will solve the problem more fundamantally but at greater cost. You can't just spread the dropouts and still use your present wheel.
