Rear regulator and glass interchange

Hey guys,
Working on the rear regulators and glass on my 69 Dart. I bought some salvaged regulators and glass since I was having problems with my stuff. When I unboxed and layed it all out I found it to be a different setup, thinking off a later A body. Looks much simpler than the 69 stuff, here is a pic of the glass for comparison.



The glass on top in the pics is the 69 stuff out of my car. Can anyone tell me if the bottom glass style and regulator will work in my 69 or am I better off trying to repair my 69 stuff?

Thanks
