Drip Rail Molding Question

I went the other way, from a vinyl top to a plain roof on my 73. The drip rail mouldings held down some remnants of the top. When I reinstalled, they were a bit loose in places. It wasn't hard to tighten up to make them fit tight. Based on my experience, I think that your trim will fit tight in the area where the canopy vinyl crosses the drip rail. Fit from the top down and be prepared to use a little extra muscle to get that part of the trim down.
