Correct, I did modify the rear radiator shroud and wheel liner. Here is an after pic of the rad shroud with the cutout areas highlighted:
I don't think there would be much risk of stones/debris hitting the radiator, I would think most of that would be directed towards the back of the car. If I get ambitious I'll put some aluminum mesh there to protect it better.
Got the wheels on and got it off the jacks for the first time in 2.5 years, I have a suspension alignment booked, so just some final wiring and tuning to finish up and it will be done. Well, who am I kidding, it will never be done, but at least it should be drivable now, assuming I haven't completely cocked something up.
