Wishbone ball joints and bushes

[ecoangel]

Looking into replacing the wishbones on my Fulvia - understand that S2 bushes are the only ones available and these require a different bolt size when adapting to a S1 car. Are there also size differences of these and the ball joints between 1300cc and 1600cc wishbones? I am thinking of the tubular variety not the later pressed steel ones. Did the 1.6HF and 1600HF have the same joint set up?

S1 and S2 HF had the same top ball joints
S2/3 all variants had the same bottom ball joints
S1 had different bottom ball joints.
