Snap in glazing

Recently bought a mobile home and need to replace some missing and dry rotted snap in glazing. The ones I have are identical in measurements to 55-172 you offer but as you see in the photo and diagram I drew the front lip has a 90 degree bend that slides into a lip instead of the curve of the 55-172. Do you have anything like this or would the 55-172 work as a substitute. Is the 90 degree bend necessary since the window grid clips are held in by the glazing? Thank you in advance, any help you can provide is greatly appreciated.
