1.7.3 Bukkit JAR Build?

I've downgraded to 1.7.3 and looking for the server software to make a 1.7.3 server so my friend and I can play whitelist on the server. Haven't found one yet! Please help!

 

I'm hoping this is allowed, but I was unable to find the bukkit build for that version .
but I found a canary mod link. And I know you might not want to use that , but why did you guys downgrade to that version of minecraft?

 

Well, my friend and I liked the simpler times and wanted to play together on whitelist for a little fun survival with 1.7.3, but can't find 1.7.3 vanilla or craftbukkit.

Oh and if I get the 1.7.3 canary will it over-wright that with the latest by default?
