I am not that familiar with SB Cobras but I don't see why you cannot use any type of after market pedal box. I used a floor mounted Tilton Racing pedal set with remote CNC reservoirs. I have a Tilton Racing hydraulic throw out bearing also so I use three reservoirs and master cylinders.
For a steering column I used a plain steel IDIDIT column. It's wired for turn signals, flashers and horn.
