67 Barracuda Door Lock Ferrules

Looking closer at the pics, it seems like the passenger side hole is smaller. So I pulled my ferrule out of the drivers side and it still fits loose on the passenger side. The link Dana67Dart sent says theirs is made for a .450 hole. I don’t think they are that small, so will order a cheap set of calipers on Amazon to get an exact size. My other set got stepped on - ouch.
