I can't find them on their curse pages. i am making a private modpack for my own use and I need these mods.
Why don't you make a pack for (at least) 1.7.10?
1.7.10 nerfed and changed a lot of mods.
1.6.4 mod list
"We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far."
Still doesn't have extra utilites for 1.6.4
The MCF Mod List for 1.6.4 has links for all of the mentioned mods.
However, if Extra Utilities is the only one you're still missing, here's the forum thread for it, which includes downloads for "1.6" (I presume that means 1.6.4, at least for the latest of those): http://www.minecraftforum.net/forums/mapping-and-modding/minecraft-mods/wip-mods/1443963-extra-utilities-v1-1-0k
Already got them from another modpack.
