vin rivets

The VIN rivets on my 67 parts car (door jam) look like regular stainless steel rivets. Nothing special about the shape of the rivet head.

Are 67's also flower shaped?

Edit: Looking at that last link... "1968-1974 All vehicles - NOS rivets!" So maybe 67s are just plain pop rivets.

Well, it looks like 67s had the pentarivets. Either the ones in my 67 parts car were replaced or ??? (bad eyes?)
