The ATR shocks info is in the Alternative Parts List on page 7, accessed through the thread at the top of this forum. They are sold as a Morgan 3 Wheeler kit for front and rear with the very original numbers of ATR MOG 001 (front) and ATR MOG 002 (rear). That includes the spacers for the mounts. Dampertech are the agents for them in the UK and you can contact Dave on dave@dampertech.co.uk . I am sure he will be able to let you know how best to get them in the USA.
