differences in 68 and 69 Cuda doors

Thanks to all you guys. My glass does fit well in the window track/mechanism and I know the glass was a 69', so 69' for both, and I know that I have a 68 door. Thanks for the exploded view of the 69' door mechanism.

I still have 2 bolt holes in my 68 door that go to nothing, and I'm wondering if the end of the 69' door simply never had these due to changes in the window guide/mechanism. I still would like to get a good picture of the end of a drivers side 69' barracuda door to see if this really is the case.

Thanks again to all for the help on this.
