The other issue here is that with it being engine swapped, a another reasoning for the wof man saying no deal apart from not matching CERT plate is 99% of the time that manual conversion would probably not involve using all OE components to convert to manual. Wether that be a adapter plate to fit OEM gearbox, custom trans mount etc.
Better case for argument here would be something like my s14, only certed for suspension mods but stock motor and auto gearbox. Manual swap would require CERT even if I used all OEM components And didn’t change the brake pedal because it no longer matches CERT plate, and the rule is it must match the cert plate.
However if I wanted to refit all my stock parts, get the cert plate removed, then manual swap using OEM parts and retain the auto brake pedal then GG I guess, but fuck that because you’ll probably fit the manual pedal so You wont stamp the brake pedal when youre trying to do clutch kicks.
-loophole would be non certed car converted to manual using 100% Oe non modified parts that still retains the OE auto brake pedal And the clutch pedal box/mount is not part of the brake pedal box / mount.
-there are cars out there than manual and auto pedal boxes differ as they’re all in one (Early commodores etc) so swapping to that would be modifying a braking component. And you’d also find that pedals will probably touch/ be too close to use nicely etc.
WOF guys gonna probably refer you to certifier as that way liability is removed from him.
great discussion point etc, but legal answer is gonna be just get a cert, it ain’t that hard.
