So I had my targa off for the first time in years and attempted to secure it in the hatch. I assume it goes in the same orientation as on the roof as that's the only way I could get it to fit. My problem is there is nothing to clip the back of the targa into the back of the hatch. The two securing tabs in the back that fold up and down appear to have a little notch in their center as if something is supposed to snap in them that will keep the top from shaking around. The back underside of my targa is completely smooth and has nothing to snap into the holders, so it just lays on top of them and slides around. Am I missing something?
