Thanks chaps. Re the shocks....these are new, standard Herald so non-adjustable. The spring is standard too. Usual trick is to remove 4 leaves to compensate for reduced weight of the Midge body, however, when I did this, the resulting camber was excessive, such that on full compression, the tyres rubbed on the inner wings. After much experimentation, I finally settled on a return to a full set of leaves, i.e. back to standard. Bearing in mind though, that the spring is over 40 years old so it has lost much of it's temper, and consequently a lot softer than original. I have used the string method to align all 4 wheels, and am reasonably confident that the wheels are pointing in the right direction. I will be giving this another try,before I go to the expense of changing adjustable shocks . Thanks again, Mike.
