Hi Gerard, these were BOGE shock absorbers – I bought them on Ebay –
<h1 id=”itemTitle” class=”it-ttl”>JAGUAR XJS 3.6 Shock Absorber (Single) Rear 86 to 91 Damper Boge Quality New</h1>
I also thought about fitting an anti-roll bar but fitting the new shocks has made a huge improvement to the handling and I don’t think I can be bothered!
