Mopar B body and Dodge dart disc brake pattern different?

My buddy bought a set of mopar rallye wheels...They fit my 67 B bodt but will not fit a 69 Dodge dart?So whats the difference?|||Heres the deal. All A bodies (dart, duster, valiant, demon etc) had 5 lug 4" bolt circle until 73, when the disc brake ones went to the 5 lug on 4.5" bolt circle. All B bodies had the 5 lug on 4.5 inch bolt circle. Some folks(me) have converted older A bodies to B body disc brakes and was able to then use the B body wheels. Mopar rallyes were made in both 4" and 4.5" bolt circles.|||both the above answers are right the bolt pattern is different on those, i got two sets of rally,s for the big pattern but none for the small pattern,that's why they wont fit it,and when you switch to disc brakes you have to use 68 or newer wheels that came for disc brakes or they wont clear the rotors,good luck.|||A bodies have a one inch smaller bolt pattern than a B body up until 1976|||The bolt pattern on both should be 5 on 4 1/2. unless it is a clearance issue ??
