I hope I have the right answer in my head, but I need some input from someone who has done this. A lady friend tried to replace her rubber cowl and bent one of the hinges soooo now it has to be replaced, question is when the windshield is down will I be able to get to the nuts that are on the back of the screws, I can get to the others after I break off all the crude that was sprayed on from the factory, any hints?oh its a 89 wrangler
