Help!! Insurance not paying to fix!!!

I had good luck when I ordered my 66 Dart Windshield,they found a brand new one in 1 day.I had to pay cash,cause the windshield was broken when I bought the car.They pulled the old one out,installed the new one with the original gasket(they also used a sealer)Done!I was surprised they even found a new windshield,let alone in 1 day!Standard Auto Glass.Good Luck!
