I have a 74 dart sport and I have had this issue with no solution. My drivers window has play between the fabric trim that's screwed to the actual door and the interior trim. My passenger doors gap is super tight and has no play while drivers is like 1/4 to 1/2 and if I max out the adjusters up top then the glass is sticking out too far. Looked at the assembly and everything is in good shape. It just seems like the inmer and outer door shells are supposed to be closer.
When I got the car that's how it was but I'm not a fan of the glass wobbling around whenever it's not fully up.
