Well you kind of changed the problem now, originally you made it sound liked the rad support was hanging by both fenders evenly about an inch, that is not a big deal and very common if the car sat on stands for a period of time with the motor in. But now I'm assuming you bolted the support down then placed the fenders on and the right one fits and the left one doesnt, that is a very different problem, are all of these parts the same ones you took off the car? If so check all your left side body bushings and make sure they seated right, the one under the center of the door can get hung up easy, an easy way to check body placement is a bar across the bottoms of the frame then measure up to the pinch weld on the rocker, and no based on your new pics I would not pull the fender down with the bolt you will just bend it. Start double checking everything something is not sitting correctly
