amazingly I was getting bolts at Lowes the other day & found a display of automotive bolts, screws and pin connectors. They were in the same row as the bolts, directly across them in metal drawers. I was shocked that they had them, but happy!
Are you talking about the small barrel nuts for the hood and trunk letters? I picked some up from a vendor at Carlisle after I bought my hood letters. I still have the package and can get you the information from it if you want.
