Button Guides for single-hung Viking aluminum window sash

I am looking to order 30-50 button guides that assist with the sash sliding up and down within the fixed window frame on single-hung Viking aluminum windows. I have attached 4 photos that hopefully will give you an idea what I'm looking for:

1. Button guide head that slides against the window frame.
2. Opposite end of Photo 1 showing "push-in securing catch".
3. Diameter of button guide head = 7/32".
4. Diameter of hole in sash frame that guide fits into = 5/32"
Overall length of button guide is 3/16".
