"Project Satan" '68 Dart

I thought that the only difference between 67, 68, and 69 doors is that in 68 they changed the lock position inorder to avoid theft and otherwise kept the 69 doors the same., how can you tell a '68 door from a '69?

Thanks for all the kind words of support and complements on the roller, no more getting distracted im going full speed ahead on the car.

Gutted the passenger side door today, sanding it down tomorrow, was a lot easier the second time around to gut.
