Added how-to any ideas to improve it or different ways to do this would be appreciated comments are also good or if you try it yourself let me know how it works out Update 1! complete here is how you do it i have used the plastic screws that hold the autobot laptop to the box but any piece of solid plastic could probably be cut to size if large enough the larger of the black pieces that hold the the supreme class transformers to there boxes would probably also work (there thickness varies a from figure to figure in my experience though)(used wave 1 voyager rotf ironhide do not know if this will work on any of the repaints or remolds) hold it up to the arm and score it where the holes are to make it look like this you are going to make it so it will fit in the hole loose fit it till it fits properly in the hole (you may want to carve out a 2nd hole for the back hole also up to you) the back hole can used for friction to prevent it form loosening as seen with out making a 2nd connector should look something like this once it fits well place it in the roof like so there is an area right under the hinge for the back of the cab (if using different piece of plastic loose fit this part first) then pace it back in the hole and tada your done also can store in truck mode loose Addendum fyi it also fits minicon ports (this also applies to the gun that is usually on that side) so the gun doesn't have to go to waste
