Difference between A1 and A2 front track?

[mardak at cogeco.ca (Mark)]

Anyone know the difference between the two front track measurements? 
Cathy has an A2 Jetta that needs a tow, and I need to know if it'll fit 
to my dolly.  (I haven't gotten around to making the "attachment" 
that'll convert it to a traditional tire-strap-type dolly when needed...)

Thanks!

Mark.
