I would not attempt to remove an old windshield having watch the glass company remove mine to replace it after it was shatter by a rock.
When shopping for price it also varies from shop to shop but also if you have insurance or not. I had a windshield replaced last year on my daughters car. I had taken out windshield coverage with a 50 dollar deductible. Having made two other windshield claims in the past year, I was debating if I wanted to go through the insurance company and take a risk of being dropped. I called three different glass shops and all three asked if I had insurance when I said yes they quoted me a price and told me to call my insurance company and bring the vehicle in and they would file the claim. I then called back a day latter and asked for the same thing and this time I told them I did not have insurance. The price was 100 dollars cheaper then with insurance. I told this to the insurance company but they did not seem to mind getting reamed by these same glass companies. I paid out of my pocket to get it changed to avoid being dropped for excessive claims.
