differences in 68 and 69 Cuda doors

I know there have been past threads about this, but I need to see pictures that clearly show the differences (if any) at the end of a 68 vs. an 69 Barracuda door-drivers side please (not the hinge side).

Reason, I feel when I got my car it had 68 doors put on a 69 body with 69 window mechanisms and this is leading to me having issues with rolling up the window (feels like it is missing some internal stabilization) and with aligning the door window to the quarter window.

Another question: Are the door widow mechanisms the same for the driver side 68 and 69 barracuda or did they change with the year?

Any help on either/both of the above will be greatly appreciated.
