So I ignored mike-tracy's stellar advice, and ended up with two symmetrically spats. This was most likely a poor choice on my part.
So I used the mounting holes to bolt them together, and then cut them equally
Not TOO terrible...
This is the left over middle section.
This is my most likely faulty logic on this. Notice how the middle section has an indent for the muffler tip of the prelude.
I was going to try and heat gun this thing out, but I didn't think it was going well. I wasn't sure that having a huge indent in the middle of my rear lip was going to look good. And i'm still not positive that having split them in half was the way to go either.
In any case, this is what i ended up with.
Now, it's still going to need a lot of shaping, and i don't know how to make the inside ends (not by the wheels) not just suddenly end in the middle of my bumper. So suggestions on this please!
So here's the passenger side.
The way the bottom of our (or at least the 93 LS bumper) has a indentation at the bottom. So I decided that to mount this thing, i'd need to double stick tape (temporary) the section closest to the wheel. But, the indent was causing the spat to not line up correctly. To deal with this, i decided to remove some of the material that made up the top part of the lip.
I cut out that top surface to approximately the red line in the picture. This is part of it removed.
After that I kind of gave up on life and packed everything away until I had a better game plan. I'm not sure if i can salvage this or not.
However, in the process of screwing everything up, i found this.
So, hopefully that's helpful to some one. I'm pretty sure it reads:
