The ones I have that would make speedometer read slower are
.9743 corrects for reading 2.6% fast
.9444 corrects foe reading 5.8% fast

The .9444 would be the closest

3.07 divided by 3.21 = .956

You will need to make sure there is room to add an adapter. The reducer will move cable over about 1 1/2 inch and add about 3 inches to overall length
