heres a TRICK I learned here on the bolt, if your hinges are ok..take a chunk of 4X4 lay it the radiator support to hold your hood open then loosen the hing bolts and push the back of the hood down and then tighten them back up ...solved my hood lifting in the rear problem in like 10 minutes.
give it a try it may just work for you also!
