Snap in glazing

A home owner from Sonoma CA says:
Attached are pics of failing snap in window glazing. Failing on southern exposure - others are OK. 25-30 year old Viking windows. Can't find profile on your site. Are others available. Pic of profile included. 5/8" on flat exposed side.

We believe you may be able to use our 55-029 snap-in glazing bead as a replacement for you. The legs are shorter than yours, but I think this would still make a good replacement. Look it over and get bacl to us with some thoughts.
