Many Oldsmobiles from the 70's and 80's had a trunk lock cover emblem. When you bought that new emblem from the GM dealer, rivets weren't included. Also there is no listing for them in that emblem group in the Oldsmobile parts book. How can I find out which rivets were used to install those emblems? If I know the proper rivet to use, I may be able to find a vendor that has them.
