I don't doubt for a min. you guy's alignment issues, but I find it hard to believe also that a few passes (or none in some cases) on mild 60' cars can bend the actual brackets, I think some looing into other areas might be in order.
As stated before....pulled them off an axle was even again so that tells me they are the issue and was push 600hp on mt street et pros and it was enough to bend an axle shaft
