So how about that, front wheel flew off!

After you get it back together, thread a lug all the way down on the stud, in one of the pictures it looked like the lug had like a 1/2" until it seated.
The rims you have are uni-lug and requires the lug to engauge almost all the threads to center the wheel.
You can also stick a lug in the rim off the car and see how much room you have left, should be about 1/8" shy to the mounting flange of the wheel.
