magnum 500s on a dart?

What upgrades would allow the magnums to work? I have a '68 dart that I'm just starting a look at rims and didn't realize that the bolt pattern would be so different. What kind of a cost am I looking at if I opt for magnums or Ralleyes in addition to the rims?

I'm going to be upgrading my Dart to the Large Bolt Pattern (LBP) and have been checking into different options.There's a couple different ways to go depending on what you have for brakes and rearend already.If you have drums on the front,a good and probably lowest cost option is to go with the 73-76 a-body disc brake setup which requires changing the spindle,upper control arm,master cylinder and porportioning valve then adding the rotors and calipers.This will give you much better braking and cheap and relatively easy parts availability.

If you have the factory disc brakes on the front you can keep everything else but swap the rotors to 66 style Mustang ones which have the 5x4.5 LBP bolt pattern and can be modified to work with the factory a-body disc brake spindle and caliper.There's a thread on here in the steering/suspension tech forum about it and that's what I'll do with my car when I get to it.

If cost is no object,SSBC has a complete kit for disc brakes with the LBP which looks first class but a more expensive option.
