control arm (upper?) shims - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So I am scraping and cleaning and scraping and cleaning my 71 these days and occasionally a peculiar item shows up that looks as if it needs to go somewhere.

Last week I found a shim, sort of a square U shaped deal, not sure which side it came from. Was this probably a control arm shim...and might it (and others) be the reason why my truck was only rubbing on one side when lowered last week?

What's the deal with these. Are they known to come loose and fall out over time?
