Windshield Install/Remove/Clips/Details

A couple of questions on the clips. I am getting ready to install the windshield on my 74 Duster. You mentioned that the 5 clips in your set were like the original ones that you took off the car. I looked at my originals, and they look like the other 18 in the set. Not sure if I should proceed to order 18 of the others. Had a nice talk with a guy from Precision yesterday. He wondered if your trim was original or not. He said I could check the trim by putting a piece on before installing the windshield with a few clips installed and see how it lies on the body. Much easier to remove it with no gasket in the way. He said the gasket shouldn't interfere with the fit of the clips. Thinking of ordering the extra clips anyway just so I have them in case things don't go smoothly. Called a couple other places like Detroit Muscle and RT. They didn't have anything to say about the clip issue. Thoughts on this??
