vanagon?

'93  audi S4 alloy wheel - 7.5Jx16 ET40   5x112     (7.5" wide with a 40mm
offset)

'96  audi a4 alloy wheel 7jx16 ET45  5x112     (7" wide  with a 45mm offset)

and  what size spacers would i need for the fronts?  they would be going on
a  2wd.  and i would be getting the center bore  machined.
