I purchased a weather stripping seal "kit" from one of the larger Mustang after market parts suppliers and finally got around to replacing the door weather strips. Passenger door will close if you give it a little extra push, drivers door not at all. Strikers are adjusted so that the door sits flush or with the body contours. Pull the seal off, door closes easy (same as if the original seal was installed). It obviously an issue with the door weather seal and not an adjustment. Where have you guys bought your door weather strips at? Who sells a quality piece that is OEM that worked correctly that didn't require slamming the door so hard the interior panel pops loose? Car is a 1979 Cobra...
