I once traded for a Brooks Swift titanium saddle with a broken tensioner bolt. I emailed Brooks about how to fix, and they told me they would repair it for free if I would ship it to them. So, I shipped it to England and got it back about a month later, good as new. Unfortunately, it didn't fit me, but I was able to sell it for a nice price. If you don't want to ship it to England, you could probably buy a longer bolt at a decent hardward shop. Make sure that you get stainless steel.

If you need a wider saddle to fit your sit bones, I have the same issue. I rode Brooks B17s for a while until I traded for a Fizik Vitesse, which is identical to their Aliante model but wider. It was so comfortable for me that I eventually put Vitesse saddles on all of my bikes. They also weigh half as much as a B17, and can be bought on eBay for inexpensive prices if used.
