Could anyone help? I am sailing my MG Spring back from South Brittany to her home port of Glasson in a few months time. I need to weld up / fabricate a launch trolley that can be pulled up the slip to retrieve her and have no means of measuring up the pad positions etc. Has anyone made any measurements of an MG spring for the purpose of building a trailer. If so I would appreciate any informatioin you might be able to provide.
