I don't know Kevin.
But I do know a fellow Insighter here in east TN that has a leaking rear "shock". He just ordered the pair. If my information is correct your outta luck now

There was only one complete "set" (4, 2 front 2 rear) in stock on this side of the pond.
Better get yours ordered now if their really needed, they'll have to be manufactured and it might be a few weeks delay.
HTH!
