Cheaper and easier to buy a new one..... contact Safelite...new ones run about $110-150. Also, you never stated if this is for 2dr, 4dr or convertible.
It's a '68 convertible. Other parts needed as well. - passenger side mirror - blue steering wheel - blue door panels - grille - seat belts - window cranks
Like George said, check your local glass shops, they can supply the windshield. Even here in Fargo ND, it is in stock. Good luck with the psngr mirror. Window cranks should be available as repros, as well as the door panels.
i have some blue seat belts from a 69 GS. they are a light blue. do you want the larger buckle or smaller one? i dont have a complete set though.
