Update… I bolted a new and old hinge side by side on boards and decided the new hinges were the wrong length in a couple of places which caused the movement to be totally wrong. LMC offered to take them back for a restocking fee (it’s been a year) but I couldn’t do that in good faith because I ground a little on the passenger hinge in an effort to remove some rubbing. Plus, I put my old hinges back on and used the new springs.
