Earlier this year I found out that the windshield assembly on my '24 is supposed to have rubber seals (mine were all missing).
I bought a full windshield seal kit from Lang's earlier this year and installed it.
One seal fits between the cowl and the bottom of the lower windshield frame.
Another, "h" shaped seal, fits between the upper and lower glass.
There are also a pair of seals that fit into grooves in the upper part of the windshield posts and seal against the sides of the upper windshield frame.
Now that it's getting cooler, I can already tell that the new seals are doing their job, there is much less intrusion of cold air through the windshield.
