Thanks, I will look up that stuff. As per the filler strip, in a 70 Dart service manual, the gasket channel that the windshield slides into has a filler strip in the bottom. May be irrelevant with new gaskets.
So it seems that its based on the manufacturer of the gasket if it has a self locking strip or a separate locking strip. Like on one site there are different options (1 or 2) that fit 67 - 75 or something like that but only one has a locking strip.
I attached a pic with and without its crappy vinyl top and one of all the " toys". Definitely not putting a vinyl top back on....hate it
