It's really hard to find subtitles that specifically match the words in the English dub. Most torrents have the English subtitles for the Japanese version. The Japanese version subtitles use different words when translating from Japanese, which isn't adequate when watching the English dub, where the dialogue is different from the Japanese sub translation. But I was able to find perfect subs for dub uploaded by xmorobertson on opensubtitles.org. I thought it would be a good idea to make it into a torrent, but note I'm not the creator. Please, check out xmorobertson's profile and thank him for his creation here :)
I tested this subs with this torrent: https://1337x.to/torrent/932641/Cowboy-Bebop-1998-720p-BrRip-DualAudio-English-Japanese-HD-1-26-Complete-Season-KoTuWa-v2/
Here's is subtitle for sub, which doesn't match dub
