Ive never installed a -63 windshield. I can imgine in its 10x nore difficult than a 64's. Im proud to say that ive successfully installed more windows than ive broken. All i can suggest is to have at least one buddy, preferably two. Go slow, dont panic. Ease it in there with even pressure on the outside. If it starts to bind or push out on one side dont force it in. Just start over and maintain patience. I tried to compensate by pushing and smacking my buddys Longhorn installation one time with the chrome trim. It broke. It started to pop out on the passenger side. It was way more frustration than it was worth. The aftermarket rubbers tend to be a lil too long causing bunching in my experience which makes installing a window that more difficult.
