I have the flywheel and clutch off a gen3 GA70 supra at home. But the pressure plate is TRD and the clutch plate is brass button. I probably have the original organic plate somewhere but it was probably TRD as well.
The 3T-GTE flywheel does bolt up to a 1G but the clutch is smaller, by half an inch i think (9"). I used a 3T setup on my first 1G and it did the job fine.
