I converted the Thundersnake from Targa to non targa. My car had been repainted with the targa off, so I had nice paint under it. Not sure on a factory car. There will be a bunch of rivets. I just took mine out and clear siliconed the holes. You can barely tell and I'm not building a show car anyway. You have remove the support plates on the B pillar. Also, since the support plates are there, the window trim on the top of the quarter window is cut short to clear it, so you'll need to get non-targa trim. You'll also need the trim strip that covers the B pillar, with the body color stripe inside it. And the only other thing you'll see, is that the t-top trim on the roof, has black tape on the back of it where the targa sat, and it's a pain to remove. You'll also want to get non-tagra B pillar INTERIOR trim pieces, because the factory ones are really fat to cover the support plate. That's about all I can recall right now. Hope this helps.
