What stood out here was that this is apparently a Tundra rear axle. And it doesn't look that wide. I'm not sure it looks any wider than the Tacoma one at all. The Tacoma body must be quite wide in the fenders. I'm assuming the GX/LC250 is similar. They must be darn close to full size width at the fenders.
