Why no fit?

Doing the math:

Fronts:

8" wheel = 203mm
half of 203 = 101mm
40mm offset means
61mm to outside of wheel
141mm to inside of wheel

measured distance from hubface to outside of fender = 64mm
measured distance from hubface to suspension = 170mm

So our 40mm offset 8" wheel should be 3mm inset from outside of fender and have 29mm of clearance on inside.

Rears:

9" wheel = 240mm
half of 240 = 120mm
if we switch from a 20 to 40 offset...
80mm to outside of wheel
160mm to inside of wheel

measured distance from hubface to outside of fender = 90mm
measured distance from hubface to trailing arm = 170mm

leaving 10mm both inside and out.

That all sound right?
