Lighting Socket Mount for 5/8" diameter spud

[SamIam]

[FONT=Arial, Helvetica, sans-serif][FONT=Verdana,Tahoma,Arial][SIZE=-1]I bought a 1K Colortran off ebay which has the mounting bar, but the no clamp or socket for mounting. It has a 5/8" hole in the bar.

I'm also thinking about using it on my Zara slider to mount it on C-stands.

Anyone know where I can find a socket to attach? [/FONT][/SIZE][/FONT]

So you've got a hole in the yoke but no c-clamp or baby socket mounted?
Is this what you need?
