80'' springs

[klonk]

Ive been checking out the springs for klonk .I checked the workshop manual found the freecamber measurement 4'' approx. I then measured klonks ones and found that they measure 6'' for front and rear. klonk has 2.5'' fronts and 1.3/4'' rears. Is the 4'' measurement for earlier models, or am I missing something?

Cheers Steve
