Here's My Spline

A home owner from Mexia, TX says:
Here's my spline. Did you just hear Bill Ingvall's voice in your head, like I did?

I digress...this is the profile of the plastic snap-in glazing spline for my aluminum windows. I have much that needs replacing and I can't seem to find the correct type anywhere. Do you know how to identify a part number for this particular style? or where I can obtain some?

Thank you for reaching out to us. Your glazing bead looks very similar to our 3ft Snap in Glazing Bead, product 55-185-3. This also comes in a 6ft length, product 55-185. Please compare your measurements to our detailed drawing and let us know your thoughts.
