Rubber glazing gasket for 1968 aluminum sliding window

Question

Any idea what part I need?  I have several windows that need this glazing gasket replaced.  The flat part is 3/8" and it looks like it should press fit into the channel of the window frame.  House was built in the Pacific NW in 1968 and has black aluminum frame windows - I have not been able to find any manufacturer markings / model #s however.

We don't sell any weatherstripping that matches this, but I'm wondering if you could use something like our 58-053. Look over our specs and see what you think.
