Where do I buy "H" channel extrusion to fix my winshield

[alamantia]

The poly "H" channel between the panes of glass in my windshield have gotten brittle and are cracking. I want to replace them with another set of poly ones or perhaps some rubber ones. The glass is 1/4" thick. I have been able to find a few companies on-line that make "H" channels but they are suppliers of extrusion and have a minimum lot runs of 500' or so. Where can I just but a couple feet of the stuff?

Look for metal sales in your area. Many have all kinds of stuff and can advise where to get it if they don't have it

Look at any RV shops in your area also, many of the windows in the older RV's also use the U-Shaped poly to hold the glass in.
