Leaf spring bushings?
I had a weird noise once. Found a golf ball.... LOLI assume you checked way down between the trunk drop off and the rear quarters?
Upper shock mounting. Bolt will seem tight but not enough to pinch the shock bushing.
....oh, I like that! Nice!Reminds me of an old story back in the day. Supposedly a factory assembler hung a miniature bottle on a string inside the quarter panel. Drove a mechanic nuts until he found it. It had a note rolled up inside that read "How long did it take to find this?" Don't know how true but I wouldn't put it past someone doing this back then.
Glad you found the culprit Durandal25
Worked in the roll shop at a steel mill for a short time and there were times I would stamp the name backwards or turn a letter upside down. Every fresh machined roll got stamped....but most of them were rightReminds me of an old story back in the day.
