Awning window bubble seal

A home owner from USA says:
I have over 15 3-part crank out windows in a 1965 condo. I love the windows, but they need new seals. Photos are attached. The little seal that runs along each window has practically no "base extension" but the portion that slides in the groove is 1/8 inch wide. I fear 3/16 may be too wide to fit. The bubble is 1/4 inch across, but may have been more (less ?) when it was "young and flexible." Do you think I need 58-135? Thanks! Wow, what a difference this will make.

I'm having trouble finding a bubble seal that matches your measurements. Can you confirm? It seems similar to our 58-135 but the size of the "T" is too different.
