Off the wall suggestion. Fit and leave the bolts JUST slack enough to allow you to settle the hood down nicely. Lift hood and flow some glue around the bolts. Close hood and settle it down again. Leave until completely set so that you can lift the hood without them moving. Either carefully mark the bolt positions, clean off the glue and refit the bolts or just fully tighten the bolts and then remove any surplus glue. Glue is your choice, but it will have to be strong!

When removing hood hinges, PV or Amazon, you can drill a hole through the hinge/bracket to take a pop rivet. Use those to ensure it all goes together in the same place when refitting. You may be able to use this trick with door hinges too.
