What disc swap kits will work with Cragar 14x6 rims?

I converted my Dart using a SSBC kit. My Cragars (14x6) wouldn't clear the calipers. Had to use spacers on the hubs and grind off the corners of the calipers so they would clear the center hub spoke welds along with grinding off some of the weld where the spokes are attached to the wheel. Not truly a 'direct" fit. They now mention in the installation instructions, that you need a 15 inch wheel for these kits. When I bought my kit 18 years ago, that was not mentioned at all.
