[A Snake]

No KMP or CSX here but I do have a suggestion for you.

It is unlikely that your foot box is the same size and shape as those two cars. As cramped as it is in any foot box, I would suggest that you first place the gas pedal, giving yourself room for your foot to center on the pedal from side to side. Then, find some way to hold the brake and clutch pedal braket temporarily in place so you can change it's position.

Next, sit in the car (preferrably with the seat in it) and move the assembly right or left to give you room. I assume here that your pedals are on a common bracket.

You will find that there will not be room for your left foot on the floor beside the clutch pedal when it is set up right. You're doing this for comfort and usability, not originality. Also remember that your feet will be to the left of your body because of the shape of the foobox and transmission tunnel. It looks awkward, but takes very little getting used to.

Distance between the pedals can be gauged by looking in my gallery at the pic called "details" if you're using the AC pieces like mine.

Height is a matter of the size of your feet and where the bracket will bolt on. Just make sure you leave room for pedal travel on both the clutch and the brake. This will also be a product of where you place the master cylinders.

Hope this helps a little.
