Ah! Yes, I did not clarify that. If I understand correctly it is what is known as a multi link system and uses a Panhard rod. The original plan was to use a Watt's linkage but there is simply not enough space behind the diff and, with the limited travel of the Morgan suspension, a Panhard will do the job.
My wife's little Subaru, with much greater travel, uses a Panhard rod.
All will be revealed when PJB and Suplex are ready to release the kit

PS. I should mention that this kit is designed for road and fast road driving. If you want something for fast road and race, or strictly track use, better to talk to Lawrie at Williams and to get him to show you just what they can do. And watch out for those pesky Spaniels
