Hemi dart front wheel size?

Thank you for the responses. This is all great information. Now, can the collective wisdom recommend what front brake setup I should put on my hemi dart semi clone? I say semi as although I am attempting to make it appear as close to a hemi dart I will be modifying certain aspects of the drive train such as a Cal Trac setup in the rear rather than the SS springs and a 572 crate hemi dressed as the original 426 including the correct manifold. So information regarding the brake set up and where to obtain same would be greatly appreciated. Thank you in advance.
