If you send me a PM Richard I will be happy to send back scans of each side of instruction sheet for SSL RS kit.
Going back to basics when new kingpins are fitted the readily available two phosphor bronze bushes within sliding stub axle each side must also be renewed. Once pressed in these then need to be lightly reamed to size such that the lubed kingpins just drop through stub axle with no discernable play. Sounds like your fitter decided to make his own noting correct ones have a spiral groove to allow grease to be distributed. Once reamed correctly and assembled they take around 1000 miles to loosen up. It would do no harm to leave the dampers off altogether initially to speed this process as there will initially be enough stiction in the suspension assembly to stop excessive bouncing.
It's important the front suspension is greased with a gun via the grease nipples (zerks) top and bottom every 800 - 1200 miles and of course particularly important when new kingpins fitted. Better there is too much grease which can easily be removed than too little, noting in your pictures on previous thread everything looked very dry.
After fitting SSL kit the previously mentioned main spring pre load needs to be wound in via the lower threaded collar, the second one just to lock the final adjustment. This is performed with car on a ramp or jacked up with front wheels removed and two C spanners are required! As mentioned your Plus 8, being the heaviest of the Classic Morgan models requires, as a starting point for the pre-load, 50mm of thread showing above the two collars (60mm if higher ride height chosen via 20mm spacer placement). I've already mentioned the final goal for pre-load which must be performed with car on the ground, and its fully described on instruction sheet anyway.
To sum up you and/or fitter need SSL instruction sheet, two C spanners and a grease gun.
