Yes, both broken near the diff output, at exactly yhe same place. I don't know how it happened ;), I'm sure it's because they becomed mechanical fragile. I often drive on grass, where the grip is good, the the rear shafts take a lot in their face
Anyway, it's unbelievable, mugen's shafts can be broken too !
