"Project Satan" '68 Dart

So what is the real position of the door locks on 1968 cars because I'm seeing some with them like the 1969 ones and some with the 1967 position, was it a mid year thing? After riding in a 1973 dart where the door lock was like the 1969 doors near the middle so when I put my arm on the door the lock would poke into my arm.

I'll have to turn down your offer unless there is a way to get around shipping because to send it down to the US to get coated, unless its really cheap, will be expensive and take longer as opposed to going to a local place.
