I found some shocks in the worshop off a jag back end xj12/6 they to are 13" open and 9" closed. Coil overs but non adjustable. Before i get shouted down i was thinking that they might be an ok stop gap for those not ready to pay shed loads for a spax/gaz/protec coil over set up. Jaguar supply plastic shims to tailor the ride height and they are cheap second hand, springs are easily avaiable in different rates.
