Prepping for Vinyl top Pissing me off

Apparently my car had a vinyl top on it when it was born. I love the look of them and am going to put one back on. I got a nice set of trim from member rockey js. Anyways whoever did the body work last put screws in the holes and welded them so I was on my back in the trunk cutting off the screws and drilling from the inside out to get the holes. it was a real *****. couldn't do it like that on the sides under the quarter window, no room for the drill.
I bolted the trim to the holes I had on the decklid cowling and just traced out the trim on the paint with a sharpie

The clips I got are a pain in the ***. the nuts dont really want to get a bite and thread onto the stud. I'm going to run a die nut and tread them before hand.
Anyways since I do not have anything to go off of is this the proper way to put the clip in the trim ??

Or does the tang on the left side of the clip point to the right ?
Any help appreciated
