Needing Pins

A home owner from Covington, LA says:
I'm looking for a top spring loaded pivot pin a bottom adjustable pivot pin and pretty certain they are 1/4 inch dia. mounts. Also top and bottom spring loaded roller or guide pins. I need these part to fit the above pics which are the 23-409 corner connectors with the 21-404 tracks. Any help you can give me will be greatly Appreciated...

I'm afraid I can't determine what pins you have from this photo. The 23-409 is compatible with several different kinds. Would it be possible to see your pin removed from the door so that I can get a good look at it?
