Another Drum to Disk Brake Conversion Question

[dj's70c-10]

I am swapping drum brakes on my 70 c-10 for disk brakes from a 72. Unfortunately, when I pulled the parts off the doner truck, which has now been crushed, I did not pull the center link. I am finding it impossible to locate this item. The salvage yards in my area no longed have these vehicles in their yards and the restoration parts houses carry the tie rod ends and connecting links but not the (drag link) center link. Apparently it is a collision item that has little demand. Can anyone steer me in the direction to locate a center link? I am pretty much dead in the water until I obtain one.
