Hi Dom, the box we made for Jeffs and a couple of other CCX's is per the CSX with the forward facing masters under the headers. You have the same problems with the CSX's with exhausts right over them. I have a couple of good pictures of the heat shields typically installed between them if you need them for reference. We also used some tight fittings either banjos or 90's to make it work but work it does and very nicely. All with the look and geometry of originals. You're right on the stops, with using a balance bar if one master fails that leaves you without anything to put pressure on the other unless it bottoms on something. I have all the pedal box parts available if there's anything else you need Bob. It doesn't matter if it's a pedal pad machined to fit an arm and a grommet or the complete box with masters to match your slaves. Let me know if you need anything else. There's a few pictures of assembled boxes on my site at

You'll notice we're a little anal about details like the forge companies markings on the side of the pedal arms per originals.
