Magnum Wheels Help

Hi,
I am wanting to put a new set of Magnum wheels (vintique wheels) on my 1968 New Yorker.
It has factory Budd disc brakes and factory 15 " wheels.
I tried a new magnum rim on the front but was hitting the big Budd caliper ???
Can you fit Magnums to these cars with the Budd brakes.
Any help much appreciated.

Gavin.
