Did you drill an 1/8” pair of holes through the hinge and boot before you removed it? That is the best way to make a reference for re-installation.

It sounds like it would be a good thing to rebuild them. If you can have somebody move the hood in the midpoint up and down while you look at the pivot points on the hinges if they jiggle side to side or up and down while that is going on you need to rebuild them.
