This isn't much of a kitbash, it's really just a part swap. I switched the swords, seats and groin pieces of my Alt Wheeljack and Grimlock. All you need is a screwdriver and some patience. I did this because I used the reprolabels for my Wheeljack but the blue looked really funny. Surprisingly after the swap, Grimlock started to look cool as well. Here's the car pics first.
