As far a the SSBC piece I suppose this is setup to be a direct bolt on to a manual brake car so if you have a manual brake car you will be OK if you have a power brake car then you may need the manual master cylinder bracket & rod. You should contact SSBC to see what they require.
The pic of the Chrome from piratejack is not of a unit they recomend for Mopars, notice the much larger bolt pattern.
