Here are a zillion and one photos of 69 Novas you won't see a "post-less" or "hardtop" as they are commonly called. 1969 Nova - Google Search
You must have the wrong year or model in mind, or the car has been customized as they didn't make a 69 Hardtop Nova. There were no convertibles either, there were only two basic bodies, two door and four door. Some as you can see by the photos have chrome on the post between the door and the quarter glass, but there are none with no post there.
