shocker length varies between the zt and contempory models and the pre contempory 75 saloons. so springs must do as well in length. dont know about tourers but i had this problem from ecp when they gave me shockers that were short even though they were for the 75.turns out the contempory shocks and springs are same as zt. i eventually sorted it by buying rear shock from best of british. fitted perfect.... i made a post about it some time ago.
