Has anyone SVA'd a car with the Locost floor mounted Pedal Box. It seems to require the clutch cable to pass through a key chassis member "C". I dont like the idea of drilling a 12 mm hole in this. Also I cannot see how I can mount a return spring and the stop light switch. The SVA also seems to require the balance to be moved about for the test I was hoping to set it once and forget it.

Mine went through with an MK floor mounted pedal assembly but it has no balance bar. I believe that it must be 'Locked' for the test. as for the holes, I wouldn't worry too much it's really solid round there, especially if you have a fully welded steel firewall. Which return spring do you mean? If it's the accelerator then it's on the carb end. As for the stop light switch, put a mini hydraulic one in the brake line.
