2x40 is a standard secondary voltage - you won't lose much if you use that.

Also, toroids tend to be pretty close to the same size for similar power ratings - find one that matches teh dimensions or is bigger (as long as it fits) and you'll be fine.

Find one locally to save on shipping. virtually any brand will do.
