As said, the Hemi Darts and Barracudas dropped the K frame for hood clearance- I think it was 3/4 or 1" off the top of my head. They do sell reproductions of the proper spacers. The hemi guys claim it doesn't affect geometry too badly, but there's always people that aren't comfortable with anything other than strict factory specs. But if you're overly concerned with it, you can use the F/M/J body spindles which are another 3/8 taller than the stock A body spindles and gets you back into a comfortable range. Plus it gets you 4.5" BC discs, too; if that's something you're after...
