Got there in the end! Chasing through the slotted nuts with a tap meant they spun down the Koni damper smoothly, all tightened up last night and wheels back on. MB back on the road!
Just need to save for a garage lift so I can take it all apart again and do the job properly, new plumbing, get all the suspension etc blasted, painted, rebushed and so on.
Thanks for all your help guys
