Need help with windshield and rear window install on 67 barracuda

Well, 500Duster, that is not the same gasket I have in my car. Mine has a square shape to the outside and is flat up against the body all around except in the corners. When I got the car there was no lock strip installed and the car has no evidence that the pins for the clips were ever there. I wound up ordering a lock strip for a GM pick-up that had a chrome finish and installed it. The cross section of the lock strip was not round though, it was a 1/2 round.

I have the 68 stainless trim and I was going to remove the window this winter to install the clips so I could use the trim. But from the picture it doesn't even look like the trim will sit tight against the gasket when installed. I had planned on getting a new gasket from Steele so I wouldn't need to worry about damaging the the old gasket but I may just replace the lock strip with a fresh one (the current one is very yellowed and cracked after 10 years) unless I can find a new gasket with the correct profile.
