69 Dart Door Glass Lift Bracket Rivets

I am looking for a pair of the door glass lift bracket rivets for my 69 Dart. One of my rivets cracked and the other one broke causing the glass to fall down in the door. Apparently new window kits do not have the rivet made correctly, so you have to drill out the part and use your existing parts, but I don't have those. If you have a pair that are serviceable (not cracked), I would be interested. Thanks.
