Windshield and back glass chrome trim

I have a 1973 dart swinger and was wondering if I have to put the chrome trim back on once I install the windshield and back glass? I am not a big fan of all the chrome and did not know if it is absolutely necessary or not. If I do not need them will I be ok just using the gasket to seal the windshield and back glass? Or will I need something else along with the gasket? TIA

I just had my rear window gasket replaced on my 71' today. If it were me, I'd put the trim back on as its pretty ugly without it. There's some pretty large gaps that the trim fills. Besides, the rear window is recessed into the body. When you get the trim off and before removing the glass, you'll see what I mean. But if you can live with it, then make yourself happy.

The fella that did my work told me that the trim helps keep everything in place by way of the reveal clips along with the gasket mating with the pinch weld.

I have no way to say whether that's true or not, but, I have no reason to doubt him as he was highly recommended to me as a go-to guy that has a lot of experience with mopar window glass and has worked in the industry for 35yrs.

Perhaps someone will come along and shed some light on the purpose of the trim other than making it look nice.

The trim helps to prevent the lock strip from working it's was out. I'm going with black trim on my dart sport, so I'll be painting mine. It'll be not so shiny and lend a more modern look to it as well

Only the bottom trim on the back glass was done here, you can see what it will look like
