I acquired an old univega frame and went to put some new V-brakes on it.

I realized that the old frame and fork have bosses with the spring holes mounted to the outside. The Shimano V-brake that I bought is set up for a spring holes to be on the inside.

Is there a solution for this problem out there?
Is it possible to remove and switch the Shimano springs to correct this?
Is there an adapter that would mount to the boss and provide a new spring hole in the correct position?
Are there other new brakes on the market that allow you to mount with either type of brake boss?

or do I just try to aquire a different frame?
