I am replacing the windshield in my 67 Sport Fury convertible and need the gasket. I have prices on line from $252 Steele rubber corp. to $90. Bobs Classic Auto Glass has it for $215. Any Ideas as to what the difference is? Restoration parts has it for 195 and 90. I have called a couple of them and the person on the phone doesn't have a clue. I want to make sure I have what the glass place needs to install the windshield. They are having me remove all of the trim around the windshield. Or they will charge me straight hourly rate to remove it. 2 glass shops wouldn't touch it.
