Options for installing AMD Quarter on a '70 Dart

...The correct way would be to tuck the quarter under the roof and that may require drilling a few of the drip rail spots. Another option is to cut a small slit so the roof can be lifted slightly. Another thing that helps is to trim off some of the flange on the quarter so there is less to tuck. As long as it goes under about 1/2" it will be fine...
That's basically what I did. I didn't see a way of getting it under the roof with some trimming and I see others have had to do that too. I'm pretty happy with the sectioning job on the rocker (from the back of the door to the back). One thing I noticed with both the rocker and quarter is that any misalignment or variation in gaps existed before I started are still there after I finished. I measured and recorded the gaps and took photos before I started. I guess that means everything is installed correctly :)
