74 360 Duster Sunroof

Hey guys,got a 74 Duster I'm getting ready to part.It's a 49,*** original mile 360 4 spd car and it's pretty solid and complete,I just don't want to sink a bunch of cash into it that I'll never see again.My question is,how do you pull out a factory sunroof without tearing anything up?I don't visit this site very often,but I do check in every couple months.Thanks ahead of time.
