Finding the right size screen plunger pin

I am trying to find the correct size screen window plunger pin. As you can see by the photo, the black pin is the original which I am trying to match. The silver pin was bought as a replacement but is too small to fit the holes in the screen. The screen and window are a K&K 14 HD. Could you offer any help in identifying and making available for purchse the correct pins? I need enough for four windows. Thank you for you help. John

Good afternoon, Emily, and thank you for responding back to quickly! I would like to order two packs of the larger of the two pin latches presented above which appears to be the 70-008. Before I place the order could you confirm that 70-008 is the larger of the two latch pins displayed in your email? Thanks, John.
