more gears

I've recently bought a '94 speed triple which has a standard 5 speed box. I've read that later speed triples came with a 6 speed box. Are they interchangable, and if they are how much might it cost me to get the bike converted??? :horns:

I kept the link for reference, and keep toying with the idea about converting my Thunderbird one day.

Best regards
