Your bolts sound stripped... There are two bolts on your radiator support and one bolt up on your strut tower (if you need pics let me know). IF your bolts just freely turn, try to wedge a large screwdriver under the "bar" and try to pry it up as you turn to see if you can get unstripped threads to catch. I have cross threaded one of mine, I can get it out but I can't tighten it down..
