QuagganTekkit

I'm sorry, I meant a Tekkit Classic server. I'm still used to calling everything Tekkit from before! But I've been having trouble with the Enjin plugin on the Tekkit classic server and thought I was using the wrong version for it.

So I'm trying to start a new tekkit server and I'm trying to install all the plugins that I need. But it seems that the plugins I was given (Enjin plugin and Towny) are all versions for the newest version of minecraft. So which version do I need for Tekkit Classic?
