SBP 14" Steel Wheels ?s

I've been toying around with the idea of body colored steelies (with "dog dish" hubcaps) on my '71 Dart GT.

With that sad, I've been doing some research on the SBP 14" factory steel wheels, but have found conflicting information. Were the 14" SBP steel wheels available in widths of 4 1/2" and/or 5 1/2"? If they're available in both widths, what determined which width a car got?

My car has the SSBC disc brake kit on the front and the 14" X 5 1/2" factory Rallye Wheels fit with no clearance issues. Has anyone used SSBC brakes and factory 14" (either the 4 1/2" or 5 1/2" wide) steel wheels?

Any/all information is appreciated.
