Have any of you guys replaced the junky rear plastic window in 87-93 mustangs? Mine shattered one day when it was cold and i've been driving around with some horrible tape over the rear window. I've heard that when upgrading to a glass piece it has to be unzipped each time you put the top down. I'm probably going back to the plastic for now, I know the top part zippers out but i'm not sure about the bottom part? Can you guys help me out or point me in the right direction?
thanks in advance!
