I had the same issue happen to me yesterday, it was the last bolt, middle on the passenger side. Brought it to a 4x4 shop, they advised they would need to cut a hole in the floor and reinstall a new nut/mount. The torque on the bolt was ridiculous, only broke it free before the interior nut...
According to the Mopar 2' Inch Lift Installation instructions, the springs will bow outwards when installed correctly, I agree that it does not look correct.
