One of the problems when attempting to fit a spring to an Austin 10 is that the rear shackle is not easily accessible as it is obscured by the bodywork and rear wheel arch. The top pin/bolt in the rear shackle is often rusted in place preventing you from pulling it forward in order to get to it. Fortunately there is some give in the rubber bush, making it spring loaded. I found using a ratcheted luggage strap was the ideal solution to hold the shackle in a position where it is more easily accessible.
