Sway bar bushings and bracket

I took my front sway bar off the car to check out the sway bar bushings and replace the sway bar links.  These

sway bar bushings are kind of bushings that are molded-on to the sway bar.

Now when I try to put the bar back on, the flat end of the bushings will

not lay up flat against the subframe of the car.

What is going on?  What happened?  Does the car need to be

on the ground to reinstall the front sway bar?   Thank you.
