Rail width on a Brooks B-17 saddle

On a 1974 Raleigh Super Course Mark II Iím restoring, Iíve run into a saddle problem. The bike came with a Brooks B-17 Champion Narrow leather saddle with a rail width of 54 mm along the portion of the saddle frame where the bracket that attaches the saddle to the seat post. The saddle leather was shot so I bought a used Brooks B-17 Champion Standard leather saddle on eBay. These rails, much to my surprise, are 50 mm apart, so the bracket doesnít fit. My choices are ...
1. try to spread the rails of the Standard saddle apart the 4 mm difference and perhaps ruin the saddle.
2. try to find a bracket and seat post that accepts the Standard rails.

This is fine, don't sweat it. The 2mm deviation you're describing likely won't cause the rails to become permanently deformed. If you have a friendly lbs or co op nearby, they probably have a collection of clamps you can sort through to find a better fit (if this is a seat pin clamp, and not a modern integrated clamp).
