there is no exact spacer width taffy.
it depends on what clearance you give the conrod between the 2 halves of the crank when you press it together, as well as the clearance you choose as the correct crank end float(which is debatable) as we have discussed.
on mine the spacer ended up 8.39mm ,but i set crank end float to .2mm & .65mm clearance between the conrod & crank halves.
i said in the caption i my gallery 8.5mm but that is a guide only,remembering mine has the 20mm drive side bearing in.
