The MK2S Jag I had was a RHD and came with a full set of "spanners" to adjust the diff - I got so into the restoration that I had the full kit chromed and the box re-felted. It also came with a set of "flasher" lenses in another kit - it was a real Euro tourer (the "S" version had an extended frame and larger trunk for long trans-Euro trips).

The issue with the Armstrong "airplane" shocks was that they'd all been around so long they're just worn out - put on a new set and the difference is pretty amazing. You have to remember that they were invented before McPhearson struts were commercially available and were pretty much the best thing going for the time.
