Dart door window channel seal frustration
Issue solved and resolved. After a bit of examination, measuring and testing with a short piece of leftover seal I found that the track width was fine at the sliders and at the outer lip where the seal sticks out a bit against the glass. However, I could see that the rounded part of the seal that goes around the slider went too far and was getting tightly trapped at the corner in the track. I could see on the seal where it had been getting heavily compressed. I trimmed 1/8" off each side and now it slides in as it should. Looking at the original seal you can see that it wraps around the sliders more tightly preventing this issue. Damn aftermarket parts.
