Glazing bead for aluminum window

I have attached 3 pictures of a piece of bead I took off of a house in Spanish Fork, UT. I have looked all over this state for the bead and all the glass companies keep telling me that the bead is no longer made. I just found your page and it looks like 55-180/55-180-6. Does this appear to match to you as well. The pictures are not that great as the sun has destroyed the bead and I had to tape it together to get the pictures I took.

The windows are approximately 30 years old. I already have the new insulated units in, I just need the bead to complete the job, and if I get a match I may need to order more as there are approx. 6000 homes Utah county with this aluminum window.

Thank You and I look forward to hearing from you soon.
