HI MAC,
YOU WILL HAVE TO GO WITH PLAEXIGLASS, YOU CAN NOT
CUT OR SAND OR BLAST THE FACTORY GLASS, BECAUSE IT IS TEMPERED GLASS - TRYED THEM ALL, WE EVEN TRYED THE UNDER WATER CUTTING WITH NO LUCK.
WHEN YOU CHOP THE TOP YOU LOSE THE CURVE FROM
SIDE TO SIDE & TOP TO BOTTOM.
WE JUST FINISH CHOPPING A 1948 4" FOR A CUSTOMER
NOW HE WANT'S TO HAVE THE CORNER WINDOW AREA
FILLED IN & HAVE THE BACK WINDOW OPENED BACK UP TO
STOCK HEIGHT, IF WE CAN & OPEN IT UP FROM SIDE TO SIDE AS FAR AS WE CAN & KEEP IT WITH FLAT GLASS.
HOPE THIS HELP'S
