How wide? Crager SS Wheels

[stantheman]

I have a 68 Chevelle and my plan is to put Crager SS wheels on it. It will look old school with 15 inchers on it. The fronts will be 15X7 and I want the widest possible on the back. Will a 15X10 fit on the back and not rub? If so, what would the backspacing be? I will have to order on line or through a catalog since in my town the SS wheels are gold plated or something...I plan on Mickey Thompsons all the way around. Any thoughts would be good. Thanks
