Window tint question

So I'm going to have the windows tinted on my 70 340 swinger after my new paint job. I was told by a professional window tintor that older cars such as ours are more difficult to tint the side Glass because of this window sweeps they are more rigid than the newer rubber style. I got this information after I had already reassembled my interior of course.I did not have a long conversation with this individual I was wondering what others think can a quality tint job be put on my car without removing interior door pieces.
