72 duster disc brake conversion

Okay so i work at discount tire and my boss gave me a wheel for my car.  It just so happened to be my favorite wheel in the world an american racing torque thrust 2.  When i got my project home and up on jackstands i pulled off the wheels and tires and tried to put on the wheel to see how it looked, well to my suprise 70-72 dusters had 5 on 4 bolt circles and my wheel was of course 5 on 4 1/2 and nobody but crager makes a wheel for my car.  Anyways, my question is does anybody make a disc brake conversion kit that will turn my bolt pattern to 5 on 4 1/2 in the front, because i put in an 8 3/4 rear end that has the 5 on 4 1/2 circle. I really want to get those wheels on my car and have matching bolt cirles front and rear. Does anybody know if a 73 conversion kit will bolt into my 72 no problem?
PLEASE HELP!!!!!!!!!!!

Lots of ways to solve that problem.  Best bet is to find a 1973 or newer A body car in a wrecking yard and swap over the front end parts but you can also buy aftermaket parts to do the conversion.
