Road Brake Installation Problem

I am replacing the rear brake on a vintage bike, a 1986 ROSS. I removed the Shimano 600 brake that was on the bike, and I am trying to install a Shimano Sante. The pads will not reach the wheel rim (700c)when adjusted to the lowest setting!!! I looked at the Shimano 600 rear brake that I removed, and the arms appear to be the same length, actually there is little difference between them. The bolt, however, looks to have been bent just a little. I'm completely surprised and frustrated that I may not be able to use the Sante brake. Did I lose a part or something? The front brake exchange has presented no problem.

In the rear, there's sometimes some fudge room in the mountinghole. Loosen up the nut that holds the caliper to the frame, push the arms down/forward and re-tighten the centerbolt's nut. This may fix it.

If it's close, a bit of work with a round file may help, either to the brake bridge or to the brake shoe slots or both...but don't get carried away with this.

Sheldon (who needs a rear brake anyway), thank you for the advice and courage. I did a little filing as well as bent the mounting bolt. I got the brake pads lowered just the amount I needed. This bike initially came with either Shimano 600 or Campy Triomphe (? spelling); I'm surprised at the distance I needed to reach the rim. Thanks again.
