I agree that longer studs and spacers will make the wheels fit as the bolt pattern is the same.
In my case using the standard drum brakes the wheels should come so far out that hey should contact the fenders.
The alternative I am thinking that might work (for in the future /retirement project ) is to use Mitsubushi truck disc brakes as they have the exact 6 bolt pattern but that needs some searching.Perhaps some other chater have some information on this modification and cares to share it with us.
