Aluminum window snap in glazing

A quick learner from USA says:
Can you point me to the proper snap-in glazing for my windows?

I have house built in the late 60's with Aluminum windows. The window panes are held in by grey snap-in "plastic" glazing. The glazing is a smidge larger than 7/16" wide (maybe 15/32"??). from the leading edge to the back side of the "toe" and precisely 5/16" tall.

Any help you can offer to identify the right replacement would be appreciated.

BTW, what do I cut this stuff with once I get it in? Sissors?

PS I found you by watching your video on You-tube.

Thank you!
Kindest regards

I believe you are repairing single strength glass in metal frames. The snap-in looks like the old Capitol gray snap-in, our 55-006. Please compare our dimensions to yours and let us know if it could work.
