Photos above show the arm the comes out of the side of the underdash box and pushes on the clutch master cylinder - effect on pedal ratio unknown.
Other picture is of the clutch master cylinder next to steering shaft - the brake master cylinder is on the far side of the clutch MC lower down bolted to the firewall where you might expect it. Not clear why their positions are reversed other than maybe not enough room for both MCs near the headers. Why they didn’t just go with a pedal box that put the MCs over or under the driver feet I don’t know, but first thing would be to find out if shell valley designed it this way or not.
