Look at the individual Mods (page 1. post 1). At the end of each Mod is "Old Versions". Care to guess what you'll find there?
The answer to any question for any Mod can usually be answered by carefully and completely reading page 1, post 1, of the Mod's thread.
Another link you should click is "Dropbox Index", which is directly above all of the mods. That has more old versions to use.

Perhaps you could make the gate block not appear until after the control block is placed and opened. The face opposite whatever you right click to open the control block menu gains the gate block. I'm not sure if that's possible, though (I don't know much about programming yet, I'm just learning the basics at the moment).
This thread has been locked due to inactivity. The forums considers a mod to be dead when the author seems to have abandoned the project, and the project is three major versions behind the latest Minecraft version.
