Got the idea from Peaugh's video (the Ratchet review). Simply swapped the bumper and slide plate from Ratchet to Ironhide. That's all. The color of the bumper and Ironhide are the exact same red and I have no qualms about giving him a red rear bumper since his front bumper is also red. I'm sure I could swap more pieces (I'm looking at the elbow and calf specifically) to give the figure a bit more consistency color-wise, but I'm lazy right now. And it ain't as big of a deal as the chest plate. Anyway, throw me some comments. Edit: New pictures per requests. And as I mentioned below, I won't be switching the calf pieces after all. The front tires are pinned through into them and I simply don't have a soldering iron or anything to loosen them.
