67 Notch glass gaskets ?

Need help---Windshield gasket. I just found out that the 67 front windshield gasket I had on order with Y1 in on national back order with no availability in sight. I have everything else already purchased and cannot find another supplier for a 67 gasket. I have in my hands the correct 67 rear gasket and lockstrip on the way. Don't really want to mix 68 front with a 67 rear but I am ready to install my vinyl top & new headliner and I NEED the front gasket.
Any suggestions greatly appreciated. RAT-------
