Can you help me identify a PN for this plastic snap-in glazing for an Alenco "non tilt/sliding" window?

Thanks!

Thanks for posting! I don't know if we have this exact glazing, but please see our 55-174 and see if this matches our sample. Compare its dimensions to what you have and let me know!

I have the same glazing as shown in the picture. Alenco windows from 1986. I ordered some samples and 55-174 looks to be perfect! Fits better than the original. So pleased.
