67 notch rear window

Ron I've no experience with notchback, but the oem style on our 67 fastback is rigid as fack. It appears moulded to the shape of front and rear windows. I doubt you could "bend" to make it work.
What do you mean by "OG"?
So, what is everyone doing to replicate the 67 style notch rear window? Can I use OG weatherstrip and mod front lock strip to fit contours of rear? Or is the 68/69 trim with clips my only option? I would rather not drill more holes, but if need be. Not that that trim is easy to find anywho. Also don’t want to hack up a few hundred bucks worth of lock strip to find out
