super beetle track width

[woolbags]

Steve , thanks for the info. I think what i am after is probably the difference between the years at the spindle width ? Unless there is another accurate way to measure the track width without the rim offset variable.
Is there such a measurement ?
I am trying to figure out the difference between an early 1302 or 1303 and a late 1303 {74} as to how my 944 hubs will be effected as far as wheel clearance and offset goes.
Thanks John
