Original shock link (I think)

Hi
I am looking for an original Shock link (what I think its called) as my bike's was replaced by previous owner, Halfdaft confirmed this fact and now I am looking to find an original link to get the bike back to standard height.

I have a possible part also courtesy of Halfdaft but the owner first wants to test his new lowered setup before he wants to let go.

So I thought I would start looking for a back-up so long.
