foot rest for left foot

[Christopher smith]

Anyone have advice for a foot rest design? Really tight footwell on my 1959 series 1 even with my size 9 shoe. With RHD my foot is within a few mm of touching the trans tunnel when on the clutch pedal. I can work the pedal OK on this Tilton hanging pedal assembly. So maybe rivet or bolt a small metal angle piece to the floor just aft of the unpressed clutch pedal? What does Caterham use-approximate dimensions and location relative to the clutch pedal?

I think most of us just tuck our left foot behind the clutch pedal to rest it while cruising.
