Vinyl Top Over Drip Rail?

I put a vinyl top on my Duster, it wasn't an original vinyl top car. I used the trim that came with it. I used a v shape piece of metal to spread the top of chrome to make it a little wider at the top , left vinyl over side of drip rail, bottom of chrome then snapped under rail with no problem.Just my 2 cents worth, may be wrong but worked for me.
