How To Install Tekkit Classic Mods Required For Servers? Help Needed

[OliverThomas]

I've started a server today (tekkit Classic) and I Couldn't access any of the tekkit building supplies from the too many items grid, so I researched and found out in order to use them I need some mods. But I don't know where to get them from or how to install them. Could someone please help!
