I have a 69 that was missing one torsion rod. I got lucky and found a set on ebay cheap. Instead of replacing the one already mounted I just installed one of the new used ones. Fairly simple installation I thought and everything seemed good when my trunk with spoiler stayed open on its own. When I closed it all was good. Went to reopen and it only opens about a foot. If I use a little persuasion it will open but with a very loud grinding popping like sound on the driver side like something is in a horrible bind. I cannot figure out what I could have done wrong. Anyone else expierenced this or have any insight?
