Snap in Superseal Glazing Bead

Hi. Sierra Pacific which acquired Superseal suggested I contact you for this replacement part.

I have 13-15 year old Superseal vinyl windows that I'm in process of replacing some of the glass as they have become defective. I've cracked several of the snap in molding? (glazing?) that resides on the inside of the window and helps hold it in the window frame. This molding goes around the entire interior of the window circumference. It is Vinyl/Plastic, white, and 3/4'' wide. See pics attached. Do you have any of this material or can you obtain it? What would the cost be for a 6 foot section? If not available, what would you recommend as a replacement?

See attached pic which hopefully shows the profile better. Yes, the 3/4" is the face of the snap and is what you see when installed on the window. The leg is 1/4". If you notice in the profile the leg has a small semicircle at the end which is what "snaps" into the frame holding the window in place. Thanks.

Just ordered a few of the 3' sections and am excited to see how they work. Let you know.
