Alright guys here is my " Mini Sideshow Captain Rex". I took the 3 3/4" Rex from the ARC trooper pack and cut the top and sides of his back armor that bulges out. Then I peeled it down and dremeled, drilled, and cut a hole inside his back armor to fit one of those little high powered magnets. Then I took a Jango Fett jetpack and cut out the peg and glued in another magnet. Then I painted the jetpack to more resemble the jetpack that comes with the Sideshow 12" Captain Rex. To make him the ultimate 3 3/4" Rex you could give him ARF hips and a softgoods kama, but I didn't want to fool around too much with my only ARC battlepack Rex. Enjoy, comments appreciated.
