71 Duster hood hinges w/lightweight springs

Are you saying that you were able to pull the regular Springs down, but you are not able to pull the lightweight Springs down? In that case, it sounds like something installed wrong. If you never tried the regular Springs, then you may not know the difference. Even the light weights will be fairly hard to pull down, but you should be able to.
RogerRamRod, No, never used the regular or original springs. They were on the hinges but not loaded. So, I used a hood prop to hold up the fiberglass hood. Don't like the hood prop. Have since found out that lightweight springs were available so I had original springs removed and lightweight springs installed. Every indication is they are installed correctly on the hinges. When lightweight springs are loaded I cannot pull the hinge down, at all. The pulling down on the hinge simulates closing the hood but, I can't budge them when pulling down on them. I'm going to install the fiberglass hood then try and see if the hinges will work, closing the hood. tks for your response
