It's pretty simply put together. Framed it with 1" by 1/8 flat stock and covered using a roll of roof flashing. Sheet metal screws for attachment and tape to seal it up. I overlayed the template on the car and imported it into CAD. From there I plotted points along the curve and used the back of the trunk as a scale in CAD. I started with putting a loop horizontally on the car. I leveled it using cardboard and jackstands. Once that was together I started on the profile shape. There are 2 pieces that I attached to the bumper. The bottom shape I just kind of eyeballed. To get the metal above to bend I just welded the vertical parts to the cross piece and while it was hot I bent it around so that It would hit the roof. I did have to weld an extra 3 ft or so to actually reach the roof. After that I skinned it in the aluminum flashing.You can kind of see it in this picture. I can get a picture from inside later.

What do you do about tail light and the license plate?
The tail light is a trailer light, one of the narrow ones. It's like 1" by maybe 8 or 10 inches. The turn signals I chose initially are terrible. I bought some 4" flush mount trailer lights I have to put them in yet. I don't have a hole saw big enough. For the license plate I put 2 bolts in the sheet metal and then I put the license plate on and sandwiched it between the 2 nuts.

I'd be curious what it is like living with it. Parking and & etc.
It's not bad. Rear visibility is terrible without the side view mirrors. Right now I have the passenger side off and I don't like it. Parking isn't really a problem other than not being able to see behind you very well. Its just about the same length as my mom's 01 Pontiac Grand Prix. I usually park where there is a curb with grass overhang (I'm not sure what you call them). This way I just back over the curb and its not an issue.

Get some test results (coast-down or whatever) before other mods. To isolate the gain from that one modification.
I did a run using the instructables coast down method and excel sheet and got a Cd of .30 (vs stock .34, not verified just googled. I also had the passenger mirror off and didn't try to adjust the frontal area.) and Crr of .01285 I think one of my tires was a little low when testing though so it might be a little better than the data I got

As for 'as good as its going to get', consider truncating it less than a foot. See the Peter Brock Cobra Coupe or Dave Cloud's Dolphin.
Are you suggesting trying to follow template better and eith run a clear panel or just leave it truncated?

The tail looks delicious! Thanks for doing that!
Thank you, pretty much everyone has said positive things about it, including "normies".
