One of these sheet metal bolts sheared off. It's one of 2 that holds the trunk tension support stop to the trunk wheel well. BMW says I can only order 20 of them at a time. It's a sheet metal screw with a 10mm hex head on it. No luck at local or online hardware suppliers. Would happily buy 1 or more if you have some from a wreck etc. #6 in the diagram and it's part number 12138530118, thanks.
