I've never liked the idea of Grimlock as a car, so I decided to use the spare blue parts from my kitbashed Alt Wheeljack on Alt Grimlock. Then I just removed the visor and modified his shoulder doors to make him look a bit different from Wheeljack, and created my own version of Alt Camshaft, since I don't like the official Alt Camshaft. I love how Alt Meister looks with no decals, but it's just not Jazz without the Reprolabels decals. So I decided to use him as Downshift instead. Simplest custom yet, I just removed the visor, painted the eyes metallic blue, added a mouthplate using a cut out silver sticker, and painted the blue highlights on his upper legs black. I also created custom tech spec cards for them by modifying Binaltech Grimlock and Meister cards in Photoshop. Binaltech Overdrive was perfect the way he was, so no changes there.
