There may be some metal shims in between your rubber gaskets. Did you see any in there when you removed the radiator support? My car is in storage, so I don't have access to it, but there should be a layer of rubber then a shim or two (to make sure the hood lines up correctly when it closes) and then rubber outside. 2 carriage bolts, washers and nuts and go through the top and the nut at the bottom along with steel piece with 2 tabs to keep things taught underneath. I'm going from memory, but I think that's correct. I'll try to get a pic if I can this week.
