Disclaimer, Podcast evolved has done a mod just like this, but there were some issues with the build. I added to the idea, this being the part that holds the back of the scorpion. The issue I had was that my Tank was a bit heavy, it would take off the connectors (this leading to the Scorpion being dropped on the ground). So I added some extra parts to it so that the scorpion will not move or let gravity take it down. My scorpion has also been modified (meaning it's a bit heavier) And I wouldn't want that to hit the ground and explode into a million pieces. I've tried to take it off by shaking the pelican and nothing will budge (which is good). Hope you like the mods.
