Guys
I got the pins from John ( thank you for your generosity and kindness ) they actually came a few days ago, I finally got home from work to find all kind of goodies on my garage table, it feels like early X-mas 😀
I also got me two 1/4" and two 6mm release pins from McMaster-Carr to experiment with them, I'm also curious to see how the Cap screw will work, I will get a pair from HD to experiment.
