I had wondered what the rattling sound I had been hearing just off idle for a month was, and finally noted it was louder with AC on. For now, I just removed the AC belt and will suffer the rest of the summer (higher priorities). Maybe do a weld repair next spring and beef up the bracket. I am using the smaller SD7H13 on this car, so maybe others will crack sooner, though metal fatigue failure is statistical.
