Circuit board adapter to make Atari Jag s-video cables

[Jamisonia]

I'm looking to make some s-video cables for my Jaguar. I found a website with the pinout, and some instructions on the internet. They usually use either a reclaimed card edge adapter with 24 pins, or buy from an unspecified source. Can anyone point me in the direction of what exactly I need and where to buy it?

I used part of ISA slots reclaimed from old mobos. I made them a little wider than the end section with the video pins and keyed it so it would only fit one way based on the overhang.
