There are a number of link setups available from Pedders.
The one that looks close to Marks picture is the 4204 which has 10mm threads and 60mm between centers. They are around $52 each and are from front sway bars for Camry, Corolla, and Apollo's.
The larger 4208 is listed as the AU Ford rear sway bar link (and about 60 other cars) and can be cut to size. The threaded rod is fixed to one joint and screws into the other as shown in the picture at around $55 each. Instead of using both joints on one side, it may be possible to use traditional bushings (jag setup) at the jag control arm mount and the new ball joint at the sway bar requiring only one unit instead of two. A nice polished peice of stainless tube to cover the thread perhaps. Just a though and depends on mount positions.
Cheers,
